While some MPs are distancing themselves from the "Blairite" label, others are warning the Labour Party not to walk away from the brand of politics than won it three general elections. Speaking to CNBC on Sunday, former cabinet minister Caroline Flint said: "A Labour leader, whoever that is, needs to look to the future but not decry the achievements of past Labour governments - the achievements of leaders like Tony Blair and Gordon Brown."
Some of the best known politicians of the Blair era - including John Prescott - are attending this year's Labour Party conference. But they're outnumbered by dissenters, such as David Blunkett and David Miliband, who've opted to criticize Labour's new leadership from afar.
Even MPs loyal to Jeremy Corbyn admit their party is deeply divided. However they say now is the time to stop squabbling over the past and to start looking forwards. Speaking to CNBC on Sunday, veteran Labour MP Dennis Skinner said: "Jeremy is here to stay. He's got the biggest majority of anybody since the Second World War. Tedious Theresa is worse than Dodgy Dave. Believe me, taking that election next time will be a relatively easy exercise for a Labour Party that is united."
