Robin Cook has mounted a strong defence over allegations that he misled MPs about a leaked Commons report into the Sierra Leone arms affair.

In a book to be published by BBC's Nick Jones, it is claimed that the foreign secretary misled parliament when he claimed he had made no use of a leaked foreign affairs select committee report into the arms fiasco.

Cook, who admitted receiving the report from fellow Scottish Labour MP Ernie Ross, is accused of being able to recount the contents of the report "chapter and verse" within minutes of its publication - prompting Jones to claim he had prepared his response based upon the leaked document.

However, speaking on Monday, Cook said: "There are no contradictions. There is no lie. There is no story."

His comments followed Tory demands for an inquiry by the parliamentary commissioner into the allegations. The shadow foreign secretary, Francis Maude, has written to Elizabeth Filkin requesting she probe the claims. "It is the case that Mr Cook has misled the committee, clearly this is an extremely serious offence. I am sure you will wish to investigate this issue as a matter of urgency," wrote Maude.

In the book, serialised in the "Mail on Sunday", Jones claims he received a phone call from the foreign secretary within minutes of the report's publication. Cook, it is claimed, said enough to indicate that he had had prior sight of the report. He says the foreign secretary closed the exchange saying "remember this phone call did not take place".

Jones' account contradicts claims made by the foreign secretary who told MPs: "No use was made of either the draft or the additional information from Mr Anderson or Mr Ross in briefing the media."

Cook said Jones had no case to make. "The only thing that appears to surprise Mr Jones is the ability of us to read a three-page summary in 12 minutes. All I find surprising about that is that a professional journalist should be surprised by it. I have nothing to add to this non-story and frankly nobody else has either," he said.

Sources close to Cook deny that he misled parliament. "He did not mislead the Commons. It is perfectly possible that he flicked through the report quickly and referred to sections of it as he did so," a source said.

Maude remains unconvinced, saying that new Labour has once again showed contempt for parliament.

"Tony Blair said his government would be whiter than white, but this scandal, coming hard on the heels of the Mandelson affair, shows that Labour treats parliament, the public and the truth, with utter contempt. The prime minister needs to get to the bottom of this and quickly," Maude told the BBC.
