Fresh details about the Ecclestone Affair - New Labour's first sleaze scandal - have been revealed in Whitehall documents.

Previously secret papers showed that Tony Blair personally intervened to secure Formula One's exemption from a tobacco advertising ban just hours after meeting the sport's boss, Bernie Ecclestone.

The Government has always maintained that the meeting did not influence the final decision over the exemption - even though Mr Ecclestone was a major party donor at the time.

The Prime Minister has insisted that Mr Blair was a "pretty straight kind of guy" in a bid to draw a line under the controversy.

Claims that Mr Blair had "railroaded" the move past ministers were also strongly denied.

However, the briefing notes prepared by officials - and obtained by a newspaper under freedom of information laws - raise questions about Mr Blair's account.

They reportedly show that Mr Blair instructed his chief of staff, Jonathan Powell, to signal his support for a derogation just hours after meeting Mr Ecclestone on October 16, 1997.

The following day, Downing Street wrote to public health minister Tessa Jowell stating: "The Prime Minister would like your ministers to look for ways of finding a permanent derogation for sport, in particular F1."

On October 24, Ms Jowell wrote to Mr Blair setting out possible options which included the idea of an exemption, but also contained alternatives such as a longer phase-in period for the ban.

But five days later, she received a letter insisting: "His (the Prime Minister's) view remains that we should seek to negotiate a permanent exemption for Formula 1, backed up by a voluntary agreement with the FIA."

Following the PM's response, Ms Jowell wrote to the EU - where the tobacco advertising legislation was being drafted - seeking a total exemption for Formula One.

A spokesman for Mr Blair said: "There is nothing new here. All these issues were debated at the time."

Shadow work and pensions secretary Chris Grayling said: "These revelations blow the lid off what looks to have been a culture of deceit in Downing Street under Tony Blair.

"Mr Blair assured us at the time that there was no deception and if, as is now thought, this claim was untrue, Mr Blair has some serious questions to answer."
