The $30 million intervention

Tony Blair's expected increase in interventions in Labour's leadership battle is set to intensify the party's infighting this summer,according to sources close to the former prime minister.

Blair has made a significant entry into the party's infighting by accusing Labour of retreating into a Left-wing 'comfort zone' with no 'coherent plan' for transforming Britain.

In a 5,600-word essay, Blair urged Labour MPs to 'force people to say where they stand' if they push for a leadership contest, with Andy Burnham and Wes Streeting as likely candidates.

Blair's allies claim his intervention is 'the beginning, not the end' of his efforts to influence the party's future direction

Blair's allies claim his intervention is 'the beginning, not the end' of his efforts to influence the party's future direction, with some suggesting that his criticism of Burnham's policy proposals has 'put fire in Tony's belly.'

They say Burnham's claim that '40 years of neoliberalism' had put Britain on the 'wrong path' had 'put fire in Tony's belly.'

Blair has criticized Burnham's policy proposals, saying the party risks consigning the UK to 'relegation from the Premier League of nations.'

Streeting hits back at Blair's comments

Streeting has hit back at Blair's comments, taking a swipe at him over his 2003 invasion of Iraq.

Streeting argued that Atlanticism cannot mean automatic subservience and that Britain must have the confidence to act independently.

He also mentioned the lessons learned from the Iraq war, saying that Labour must not repeat the mistakes of the past.

Broader context: Labour's leadership battle in the context of Brexit and the UK's economic future

The party's infighting is also being fueled by the controversy surrounding the 2003 invasion of Iraq,with some Labour MPs accusing Blair of being out of touch with the party's values.

Blair's intervention is seen as an attempt to influence the party's future direction and to shape the debate around Labour's leadership battle.

Open questions : Who will ultimately emerge as Labour's leader?

The question on everyone's mind is who will ultimately emerge as Labour's leader, with Andy Burnham and Wes Streeting as the two main contenders.

Blair's intervention has added fuel to the fire, with some suggesting that his criticism of Burnham's policy proposals has 'put fire in Tony's belly.'

The outcome of the leadership battle is far from certain, with many predicting a long and bloody contest.
