The Liberal Democrats want to create an "earned route" to citizenship for migrants who have been in the UK for 10 years. How should we deal with immigration?
Labour's immigration policy would continue to tighten the newly-created points-based system and the Conservatives are proposing an annual limit for non-EU economic migrants.
The Lib Dems have also defended their claim that 80% of immigration into Britain was from the EU, something which their leader Nick Clegg said showed a Tory policy to cap non-EU immigration was "complete nonsense". Senior Conservative Michael Gove dismissed this as "bogus statistics", saying only a third of immigrants came from the EU.
Do you think an immigration amnesty would be a good idea? Do you think a cap on immigration is achieveable? What immigration policies need to be discussed?

Belgium's lower house of parliament has voted for . Does the proposal set a dangerous precedent?
The law prohibits the wearing in public any clothing that obscures the identity of the wearer. If passed, it would be the first move of its kind in Europe.
Only around 30 women are said to wear this kind of veil in Belgium. However, the Muslim Executive of Belgium says that the law could lead to them being trapped in their homes.
Should the state be able to control what people wear in the name of security? Do you live in Belgium or other parts of the world where similar bans are being considered?

Wildlife documentaries deny animals their 'right to privacy', an academic has claimed. Is this taking animal rights too far?
Dr Brett Mills, from the , admits it might seem odd to claim that wildlife has a right to privacy, but says that producers of nature shows often ignore behaviour which suggests animals want to be left alone.
He said: "We can never really know if animals are giving consent, but they often do engage in forms of behaviour which suggest they'd rather not encounter humans, and we might want to think about equating this with a desire for privacy."
Are wildlife documentaries an invasion of animals' privacy? Do you think animals understand the concept of privacy? Is it more important to learn about our wildlife than respect an animal's privacy? Are you involved in making documentaries?

BP's chief operating officer Doug Suttles said the 98-tonne concrete-and-steel containment box had to be moved, after ice-like crystals began accumulating inside it. He said BP's engineers hoped they could find a solution to the problem.
Some 5,000 barrels (210,000 gallons) of oil a day has been leaking for 19 days from the well, 50 miles (80km) offshore, since an explosion destroyed the Deepwater Horizon rig last month, killing 11 workers.

Labour is not treating immigration as "off limits" a minister says after Gordon Brown called a pensioner who raised the issue "bigoted". Do you think politicians should talk more about immigration?

Elsewhere, Mr Clegg said he would focus on the problems with the banks and the "overheated housing market". While Conservative leader David Cameron has been discussing his party's plans to create a £200m cancer drugs fund.

The will not start until 2013 at the earliest following rejection by the Senate. Has the right decision been made?
Australia has some of the highest per capita emissions of developed nations. Prime Minister Kevin Rudd had hoped the scheme would cut the country's carbon emissions by up to 25% from 2000 levels by 2020, by requiring industrial polluters to buy licences to emit carbon.
However, some politicians questioned the scientific case for global warming and claimed that the emissions trading scheme would damage Australia's economy.
The scheme had already been rejected twice by the Senate, where Kevin Rudd's government does not have a majority.
Does the decision by the Rudd government reflect changing attitudes towards climate change in Australia? Is slow global progress on emissions cuts to blame for the plan's delay?

Labour want to cut the deficit by more than 50% by 2014, protect "frontline investment" in childcare, schools, the NHS and policing and restore the link between the state pension and earnings from 2012.

The Liberal Democrats want to focus on raising the threshold at which people start paying income tax from £6,475 to £10,000, introducing a banking levy until such time as banks' retail and investment arms can be separated and scrapping the identity card scheme.

The Liberal Democrats have insisted any support from them in a hung parliament will require a commitment to electoral reform. Are you happy with the current system?
Changing to a system of proportional representation (PR) would mean a closer match between the percentage of votes candidates receive and the percentage of seats they receive. The current first-past-the-post system means the election is determined by the highest polling candidate in the constituency.
Lib Dem leader Nick Clegg says the current system "could throw up the preposterous prospect that a party that comes third in terms of votes could continue to govern from Number 10". Conservative leader David Cameron said the great 'con' of PR was that it put power in the hands of politicians not the people. Labour have said they would hold a referendum on electoral reform.
Do you think we should have a debate on proportional representation? Which voting system is better? Is electoral reform essential after the election?

over the costs of the six-day airspace shutdown as thousands of Britons continue their slow journey back to the UK. Who should pay for the cost of this disruption?
Airlines want compensation for the volcanic ash disruption, estimated to have cost the industry more than £1bn.

Yesterday, Nick Clegg, leader of the Lib Dems, said cash while board directors in financial institutions should never earn extra payouts. He added that the names of all banking employees earning more than the prime minister (£197,689 per year) should also be published.
How would you improve the banking system? What is your reaction to Gordon Brown's admission? Do you think Nick Clegg's plans are realistic? How should employees in the financial sector be rewarded?
, a report says. Do you think there is more competition to get into top comprehensive schools than to get into grammars?
report finds that in the 164 most socially selective comprehensives, only 9.2% are from poor backgrounds compared with 13.5% in the 164 remaining grammar schools, which are wholly selective on the basis of ability.
The report also reveals some of the lengths parents go to to get their child in to the desired secondary school. These included renting or buying a property close to a good school, or encouraging their children to underperform in fair banding tests, which seek to allocate a fair spread of different ability pupils to schools.
Are comprehensives more socially 'exclusive' than grammars? Is your child in a top comprehensive school? What lengths did you go to to get your child a place?

Who is right on National Insurance?
Business leaders of more than 60 top companies have backed the Conservatives' opposition to a rise in National Insurance
Gordon Brown will argue that the Conservative plans would put the economic recovery at risk by removing £6bn from the economy in 2010, and business leaders who have signed up to the Conservative plans have been "deceived".
The Lib Dems have said the dire state of the public finances mean they cannot oppose the NI increase but say their focus is on taking the lowest-paid people out of tax altogether.
How will a National Insurance increase affect you? How important is this issue? Do you have a personal experience to share?
Is it the right strategy?
The deal, agreed last month, commits the former Cold War foes to cut their stockpiles to 1,550 warheads each, about 30% less than currently allowed. It also limits the number of launchers each country has.

Have your driving habits changed due to the increased price of petrol?
One factor increasing petrol prices is the implementation of the extra duty of 1p a litre added on 1 April and a further 1p to be added in October.
The oil price is rising too. It reached a fresh 18-month high on Tuesday on growing hopes of a US-led global economic recovery. Motorists are already suffering from a weak pound, which has pushed up the price of oil in that currency, because it is priced in US dollars.
Do you think petrol is too expensive? Is petrol in your area more expensive than the 119.9p a litre average price? Have your driving habits changed as a result?

Should students be involved in the selection process?
The concept of student voice was developed in the early 1990s as a way of allowing pupils to participate in school decision making. The union says involving pupils in making judgements about the suitability for posts and competence in the classroom is unacceptable. It also says the system is being abused by head teachers seeking legitimacy for their arguments.
But the general secretary, Dr John Dunford, says students are very astute at "articulating what works well and how weaker areas could be improved in the classroom" and it is useful to have students views about interviewees.
How far should student participation go? How should pupils participate in decision making? Are you a teacher, a parent or a student? What are your experiences of student voice?
