Downing Street has defended the accuracy of its record of David Cameron's meetings with News Corporation chairman Rupert Murdoch after it was called into question by evidence given to the Leveson Inquiry into media standards.
Labour MP Chris Bryant told the House of Commons on Wednesday that a list of meetings submitted by Mr Murdoch suggested that the pair had met more often than was admitted by Downing Street.
However, Lord Justice Leveson has now indicated that the list, not yet published, may be revised by lawyers before being released to the public, and he warned against leaks by "core participants" in the inquiry, such as Mr Bryant, who have advance access to documents and witness statements via a secure computer system called Lextranet.
Raising a point of order in the Commons on Wednesday, the MP said: "Rupert Murdoch - this has been published by the Leveson Inquiry - made it clear that there were meetings with the Prime Minister on May 18, May 25, July 21, another on July 21 and July 22."
He said that this appeared to contradict the list of the PM's meetings with press proprietors, editors and senior media executives released by Downing Street, which recorded only one meeting with Mr Murdoch between May 2010, when he took office, and July 2011.
Mr Cameron's official spokesman told reporters: "Our list is based on our diary records and we believe those diary records are comprehensive."
The spokesman declined to give an official definition of the kind of encounter which was recorded on the list as a "meeting", but said that it would not include every person who the PM exchanged words with at a large event.
In a statement as the inquiry opened again, Lord Justice Leveson said: "For the avoidance of doubt, nobody should be publishing anything using the material from Lextranet which is intended to be only to provide core participants with forewarning of statements and exhibits.
"Everyone must understand that it is only the redacted statements or exhibits that can ever be published or referred to."
Lord Justice Leveson said he has redrafted his order banning publication of material before it is posted on the inquiry's website to make it clearer.
