The government accuses a rogue marker of sabotage, after leaking a SATS paper

They're the tests that have already angered some teachers and parents, and now SATs appear to be at the centre of a sabotage attempt. A paper taken today by more than half a million 10 and 11 year olds in England, was published online, with its answers, last night. The Department for Education says a "rogue marker" then tried to leak it to the media - its begun an investigation into how it all happened. Charlotte Grant has the story.
