The White House warnings, which were reiterated by other leading US-based figures, played a key role in Mr Blair’s attempt to cling on to power until at least 2008, and to groom David Miliband as his successor, The Sunday Telegraph has been told.
Mr Blair hatched his plot to stay on longer than planned after being told that President Bush and those around him would have “big problems” working with Mr Brown.
Senior officials in the US administration sounded the alert after a meeting between Mr Brown and Condoleezza Rice, Mr Bush’s secretary of state, in which Mr Brown “harangued” her over American policy on aid, development and Africa.
After the uncomfortable session, sources said she reported her misgivings to the White House, and they were sent on in turn to Mr Blair.
After taking the warnings on board, Mr Blair signalled his intention to stay on at No 10 until at least 2008, the year of the US election to choose a successor to Mr Bush.
