Looking back on the most remarkable week in British politics

A week ago at Westminster we were digesting the result of the referendum and working out what it might mean for our region's economy and jobs

We still are. And then domestic politics got very very hectic...

Firstly, it was Labour's turn.

On Monday, Labour leader Jeremy Corbyn faced dozens of resignations from his frontbench, while for two Labour MPs in our region it was a chance to step up to the Shadow Cabinet, including Norwich South MP Clive Lewis who was promoted to Shadow Defence Secretary.

His first task was Defence questions in the House of Commons at 14:30.

However, Mr Lewis had been standing in for his boss at an event at Glastonbury and was still en route back- too late to get to the Commons for question time.

On Tuesday, Luton North MP Kelvin Hopkins, a long time supporter of Corbyn's, was promoted to the Shadow cabinet as well.

The first pictures of the new Shadow Cabinet were released and I'm pleased to say in our Westminster office we could name all of them - in fact, 50% of Labour MPs in the East are now in Corbyn's top team.

Meanwhile, on the other side of the Political divide, the Conservative Leadership race was getting underway.

All the talk on Tuesday and Wednesday was of who was supporting who, and on Tuesday evening at a Westminster event, Boris backers were very keen to point out they believed he was a winner. We all did.

By Wednesday he'd got the backing of Cabinet ministers in our region in the shape of Liz Truss, John Whittingdale and Priti Patel but then something changed.

Suddenly, a number of MPs in the East were telling me they would back Home Secretary Theresa May, with many of them waiting until after her big launch on Thursday morning to declare their backing.

After she'd launched, we headed to an upmarket hotel near Westminster for Boris' launch.

For a man who normally likes the limelight, he made an unusual entrance through the back door.

He did a speech that sounded like his bid for the top job and then stunned his audience of MPs and journalists by saying he was not the man to be the next Prime Minister.

Supporters including Mid-Bedfordshire MP Nadine Dorries were in tears, and when we spoke to Braintree MP James Cleverly who had been helping with his campaign, he was visibly upset and told us he'd had an inkling by the change in tone in Boris' messages to him that morning that something was up.

However, as one door closes, another opens, and the path was cleared for South Northamptonshire MP Andrea Leadsom to launch her own campaign.

She let her supporters know of her intention via a video message and is now among the favourites to be the next Prime Minister.

But here at Westminster, things are changing fast so watch this space - there could be plenty more twists and turns to come yet!
