PM makes secret donation after 26-night stay at Sir Cliff's

Tony Blair and his family spent almost the whole of last August in the Barbados villa owned by Sir Cliff Richard, the Register of Members' Interests reveals.

The Blairs were given free use of the villa for 26 nights, although they later paid a donation to charity in lieu of rent. Downing Street declined to say yesterday how much they gave, or to which charity. The cost of renting a villa of similar size has been estimated at £10,000 a week. Mr Blair's entry says he paid all the other costs of the holiday, including flights.

The Prime Minister has also, for the first time, declared some of his wife's income. Though it does not say how much she earned, he registered royalties from Cherie Blair's book The Goldfish Bowl: Married to the Prime Minister 1955-1997, and her fees for speaking engagements in Washington, Australia, New Zealand and Florida.

A note says that the book was registered because it "makes reference to her life in Downing Street" and the four speaking engagements because they "included some discussion of my wife's life in 10 Downing Street".

The Australia visit attracted adverse publicity when it emerged that it had raised only £7,000 for charity despite Mrs Blair being paid a reputed £10,000.

Mr Blair's spokesman said he was not required to list his wife's earnings but that he had decided "to err on the side of caution".

Chris Grayling, the shadow Leader of the Commons, said: "It underlines the importance of establishing a code of conduct for prime ministerial spouses, which should stipulate that profits from such activities go to charity."
