LONDON (AFP) - Tony Blair repeatedly broke promises on making way for Gordon Brown as Britain's premier, leaving a "furious" Brown exploding like a "volcano", Blair's former deputy said in comments published Sunday. John Prescott blew the lid on the long-running feud at the top of British politics in his autobiography, serialised in The Sunday Times newspaper. The broadside piles further pressure on Brown, who at the start of the month was battered by the worst local election results for Labour since the 1960s and is facing rising discontent among backbench lawmakers. A poll of 5,000 voters in the Observer newspaper Sunday said fewer than a quarter of Britons think he is the best man to be in 10 Downing Street. Prescott's revelations come the day after newspapers started serialising Blair's wife Cherie's memoirs, while those of Blair's former chief fundraiser Lord Michael Levy appeared last month. Both contained unflattering comments about Brown. Prescott branded him "frustrating, annoying, bewildering and prickly", saying he could "go off like a bloody volcano" and said he sulked so often during meetings that they had to be abandoned. The self-confessed "old bruiser", 69, was Blair's deputy while Brown was finance minister for 10 years until Blair resigned in June 2007. He said he spent much of his time in office as a peacemaker, with "hundreds" of telephone calls and meetings smoothing out spats between Blair and Brown. Blair repeatedly reneged on promises to make way, Prescott said."He was definitely going in, er, six months, perhaps a year, certainly before the next election. When it never happened, Gordon was furious and the whole cycle began again," he said. "Each of them tried to get me on his side, complaining about the other. Tony would say Gordon wasn't cooperating with him at all. Gordon would say he'd been cheated again." Go-between Prescott told Blair to sack Brown if he was fed up with him and advised Brown to resign if he felt he had been misled, he said. "But neither could take the final step. "They were caught in their own trap. Tony knew that sacking Gordon would tear the party apart." In Blair-Prescott-Brown meetings, there were "always tensions in the air", the former deputy prime minister said. "Gordon would get in a sulk and say nothing, leaving all the talking to me, so these meetings petered out." Prescott also accused Blair of "using me" and "treating me like a performing seal". He said they did not socialise and had only seen each other once since resigning together. "We were never friends," he said. In her memoirs, Cherie Blair said her husband would have stepped down earlier after suffering a crisis of confidence over Iraq but Brown was "rattling the keys (to 10 Downing Street) above his head" and Blair wanted to secure his domestic legacy, the Times said. Meanwhile, former Labour fundraiser Levy told BBC television Sunday it would be "inconceivable" if Brown did not know where donations were coming from to help Labour fight the last general election, as he has said. This issue was at the heart of the "cash for honours" row which tarnished Blair's last months in office and centred on questions over whether Labour handed peerages to business people who gave the party major donations. Levy and another Blair aide were arrested during a police investigation but no one was ever charged.
