In a move more suited to a child in a playground than the incumbent PM, David Cameron denied that he and Tony Blair were “friends” as the pair met, ironically, to discuss the peace process in the Middle East.
The two men spoke for just 20 minutes at the British consulate in Jerusalem, as Mr Blair - who is now Middle East envoy for the Quartet of the UN, US, EU and Russia - briefed Mr Cameron on efforts to Palestinian economic development.
After the meeting, Mr Cameron, who is in the region on a two-day visit to Israel and the Palestinian territories, told Sky News that the pair did not have a "friendship".
Speaking of his predecessor, who served as premier from 1997 to 2007, Mr Cameron said: "I wouldn't say it is about friendship. We were very vigorous opponents. I remember facing him across the Despatch Box every Wednesday at Prime Minister's Questions.
"We come from different political parties, different political traditions and there are many things we disagreed about, but we both want a two-state solution and he has got a contribution to help bring that about by helping generate Palestinian economic growth.
"I obviously listen to Tony Blair's advice, as I listen to many people's advice."
He also denied that he saw himself as Mr Blair's "heir" in Downing Street.
"That's not something I ever recall saying," he told the BBC. "I wanted to be the replacement to Tony Blair and I'm pleased to say, as Prime Minister, that's what I am."
