As it happened: Javid quits amid reshuffle - BBC News
Sajid Javid resigns as Boris Johnson appoints Rishi Sunak the new chancellor.
In case you struggle to read the small print, here is the letter in full:

It has been a privilege to serve as Chancellor of the Exchequer. Since being elected as the MP for Bromsgrove 10 years ago, I have had the huge honour of holding several ministerial roles - running five departments, including two of the great offices of state.

While I am grateful for your continued trust and offer to continue this role, I regret that I could not accept the conditions attached to the reappointment. It is crucial for the effectiveness of the government that you have people around you who can give you clear and candid advice, as I have always sought to do. I also believe that it is important as leaders to have trusted teams that reflect the character and integrity that you would wish to be associated with.

The government you lead has an enormous opportunity in the coming years to transform our country. Millions of people have given their renewed trust in a Conservative government to move on from the divisions and distractions of recent years, and lead us forward into a decade of social and economic renewal. We must not waste a moment in delivering on that promise.

As you know, the agenda we have been developing over the last seven months is one that I have long supported. From maintaining strong public finances, investing in infrastructure, protecting our environment, recruiting 20,000 police officers, and boosting housing and skills so the next generation can have the opportunities they deserve.

I would urge you to ensure the Treasury as an institution retains as much credibility as possible. The team there has impressed me with the energy and intellect they have brought to delivering the shifts in policy that I have led. They are among the very best public servants we have and I hope they can continue to play a central role in driving an economic agenda that puts people and place at its heart.

My biggest hope is that this government will bring the country together, and help to level the playing field so that stories like mine are not exceptional or lucky. While it is of course disappointing that I will no longer be in the position to see this vision through as one of your cabinet ministers, I am very optimistic about our country's future. You and the government you lead will continue to have my full support from the backbenches.

I am very much looking forward to spending more time with my family, and to continuing to serve the people of Bromsgrove.
