Nobody outside the Westminster village would recognise the names of David Keogh and Leo O'Connor. One is a former Cabinet Office official, the other a researcher for an MP who lost his seat at the last election. But the crime of which they are accused concerns two men who are firmly in the public eye: Tony Blair and George Bush.

On Tuesday, Mr Keogh, 49, the civil servant, and Mr O'Connor, 42, who worked for the former Labour MP Tony Clarke, will appear at Bow Street magistrates' court in London. Mr Keogh is charged, under the Official Secrets Act, with sending the researcher a transcript of an April 2004 meeting at the White House between the Prime Minister and the President. When the document was shown to Mr Clarke, then MP for Northampton South, he returned it to Downing Street.
