Virgin Atlantic says it is still in talks with the UK government about a coronavirus-related bailout.

that billionaire Virgin Group boss Sir Richard Branson is seeking a buyer for the airline.

Virgin Atlantic said talks were "ongoing and constructive", but added that it is also looking at raising cash from the private sector.

In the blog post, he said: "We will do everything we can to keep the airline going - but we will need government support to achieve that".

He added that his luxury island resort Necker Island could be used as collateral to help secure state aid for Virgin Atlantic.

The Department for Transport said: "The aviation sector is important to the UK economy, and firms can draw upon the unprecedented package of measures announced by the chancellor, including schemes to raise capital, flexibilities with tax bills, and financial support for employees."

A spokesperson added that they were willing to consider individual firms' situations, after all alternatives had been explored, "including raising capital from existing investors".

In March, Chancellor Rishi Sunak wrote to airlines and airports urging them to find other forms of funding, and that the government would only step in as "a last resort" during the coronavirus crisis.

Sir Richard offered to inject £250m into the group last month, with most of that going to Virgin Atlantic.

Sir Richard's Virgin Group currently owns 51% of Virgin Atlantic, while the US airline Delta owns the other 49%.
