What does Downing Street look like under Andy Burnham?

So attention will increasingly focus on what Burnham in No. 10 looks like.

There are still many questions to be answered about his policies and priorities. But we’re starting to get some answers on his core team.

Rachel Reeves will not be its chancellor. This will come as no surprise to the incoming Prime Minister.

But it’s still a big deal: Reeves was not only chancellor for two years, but spent years in opposition shaping Labour’s economic course.

She could be given a more junior cabinet position – although it’s worth noting how rare it is for a chancellor to move down the cabinet.

With the exception of Nadim Zahawi, who spent only a few weeks as Chancellor of Boris Johnson, you have to go back to 1983 for examples of the chancellor being relegated to a minor cabinet role.

So who will replace her?

The frontrunner is widely thought to be Energy Secretary Ed Miliband. In January, Sir Kiir urged Burnham’s first attempt not to be returned to parliament and has since been seen as backing Burnham’s ambitions.

Miliband’s defenders argue that it is Chancellor Burnham who wants to achieve his ambitions to transform the British economy.

Regardless of his agenda, MPs argue – particularly on the green transition – he has shown an extraordinary ability to drive the machinery of government over the past two years. Gordon has years of treasury experience advising Brown.

But there are many Labor MPs who oppose the idea, particularly on the right of the party.

Some of these are enmities that persisted during his leadership. But their biggest concern about Miliband is policy: for some, he represents a shift too far to the left.

One MP said: “I think the Chancellor’s case is a big risk for Andy.

“If Andy goes with Ed, he’ll split the party from the start,” says another.

What about Wes Streetings? has been Talking about his economic evidence in recent weeksAdvocating for a vision of “progressive capitalism” – his allies are begging him to get the key to Number 11.

They argue that it would be a “sensible choice” that would stabilize financial markets. His communication skills mean he can sell big economic ideas on a human level, they say.

But there are also big risks. “Wes wants to be prime minister one day. Can Andy trust Wes to have his back when things get tough?” asks the minister.

Other names doing the rounds include Burnham’s former chief secretary to the Treasury, Yvette Cooper, and former defense secretary John Healey – although appointing him would force Burnham to make huge increases in defense spending.
