91热爆

The Department for Education says its urgently investigating the online leak of a primary school Sats test, which is being taken by 600,000 children aged 10 and 11 in England.

A source at the department told the 91热爆 that it believed a "rogue marker" had briefly placed the test on a password protected site to undermine government reforms.

The department says the integrity of the test has not been compromised and schools should deliver it as planned.

Shadow Education Secretary Lucy Powell says it is one of many "disasters the government have overseen".
