It's been a frantic day at Westminster full of twists and turns. Here are the main headlines.

• Theresa May has completed a reshuffle of her cabinet, bringing a number of new faces into her top team, although the biggest jobs have all remained the same
• Justine Greening has resigned as education secretary after reportedly turning down a move to Work and Pensions
• Ms Greening has been replaced by Damian Hinds while Esther McVey becomes the new work and pensions secretary
• Matt Hancock is also promoted to the cabinet as culture secretary while there are moves for David Gauke to justice, Karen Bradley to Northern Ireland and David Lidington to the Cabinet Office
• Northern Ireland secretary James Brokenshire quits on health grounds ahead of surgery on a lung condition
• Jeremy Hunt remains as health secretary but gets added responsibility for social care while Greg Clark stays at business despite speculation during the day that both might move
• There is a major shake-up at Conservative Party headquarters, with Brandon Lewis becoming party chairman
• Women's right groups have criticised Theresa May's decision to appoint an MP who opposed the decriminalisation of abortion to a party role representing women
• Here is a full list of the cabinet after Monday's appointments
• The reshuffle will continue on Tuesday with changes to the middle and junior ministerial ranks

But not all commentators are convinced that this represents a huge step forward.

What does former chancellor and now Evening Standard editor George Osborne, who is always free with his opinions when it comes to Theresa May's leadership, make of the reshuffle?

Laura Kuenssberg says the reshuffle did not "entirely go to script" given that of the three ministers she wanted to move, one quit, one persuaded her that he should stay and the other wasn't even asked to move.

At the end of the day, she says the cabinet does not look very different from how it did this morning in terms of its gender balance and diversity.

While this was never intended to be a transformative moment - since the key figures in the PM's top team were all staying put - the BBC's political editor says No 10 will hope that day two of the reshuffle on Tuesday, when we will see changes to junior and middle ranks - goes more smoothly.

It is now clear that Nicholas Soames, who is of course Winston Churchill's grandson, is not that happy with today's developments.

Andrea Leadsom and Liz Truss are expected to stay in their positions in government, the BBC understands.

The prime minister is likely to have conversations confirming this with them on the phone later this evening.

Andrea Leadsom is currently the Leader of the House of Commons and Liz Truss is Chief Secretary to the Treasury. Both attend cabinet.

Jeremy Corbyn has told a meeting of the Parliamentary Labour Party that the reshuffle was a "pointless and lacklustre" PR stunt.

"In 2018, the impact of Tory austerity is hitting home with the public, most tragically with the most serious NHS winter crisis yet," he said.

"And yet the government's big plan for the new year is to dodge the real issues and reshuffle the pack in a pointless and lacklustre PR exercise. It's simply not good enough. You can't make up for nearly eight years of failure by changing the name of a department."

Former Conservative minister Nicholas Soames has a typically idiosyncratic take on the cabinet reshuffle.

Let's recap on a few appointments we missed earlier.

Alun Cairns keeps his job as secretary of state for Wales while Jeremy Wright remains as attorney general.

Claire Perry is the new minister of state for business, energy and industry and, in that capacity, gets the right to attend cabinet.

The Devizes MP was seen as a protege of George Osborne. She quit her job as rail minister after David Cameron's resignation in July 2016.

But the pro-Remain MP rejoined the government last summer and is regarded as having done a good job since then as energy minister.

Shadow Education Secretary Angela Rayner has wished her former counterpart Justine Greening well after her surprise resignation.

The Lib Dems have issued a somewhat more pointed response, suggesting Ms Greening had been "pushed out".

"The only rational explanation would be that this is an acknowledgement that the Conservatives have a failed schools policy," said the party's leader Vince Cable.

Esther McVey is the new secretary of state for work and pensions, No 10 has announced.

This is a big cabinet promotion for the former minister, who lost her seat at the 2015 election but was re-elected in 2017 and has been a whip since November.

Jeremy Hunt has had some quick explaining to do after he appeared to like a tweet confirming that Justine Greening had quit the cabinet.

As it turns out, it all appears to have been a case of fat finger.

David Mundell is reappointed as Secretary of State for Scotland.

He was appointed in 2015 when the Tories only had one MP in Scotland but has retained the role even though the party has considerable more representation now after June's election.
