Former prime minister Tony Blair is godfather to one of Rupert Murdoch’s children, revealed the media tycoon’s wife.

In an interview with Vogue, Murdoch’s third wife, Wendi, said that Blair was at the baptism of their two daughters on the banks of the river Jordan in March last year.

The article says Mr Blair attended the ceremony, at the same spot as Jesus is said to have been baptised, “garbed in white”. She also says he is one of her “closest friends”.

Blair has been reluctant to criticise News International over the phone hacking scandal.

In July, it was said that he asked Gordon Brown to make the Labour MP who helped to expose phone hacking, Tom Watson, to stop investigating. Blair’s spokesman denied this.

Nicole Kidman and Hugh Jackman were named godparents to Grace, nine, and Chloe, eight, when the magazine appeared in Hello! Magazine last year.

But Blair being made godfather to Grace was not mentioned and his picture was not published.

Blair’s spokesman declined to comment last night, but a News Corp source confirmed he was Grace’s godfather.

The full interview is out on Thursday in the October issue of Vogue.
