Gavin Williamson's resignation letter in full
Gavin Williamson has resigned as Cabinet Office minister amid accusations of bullying. Sir Gavin says he "refutes" the characterisation of his conduct but that the claims were becoming a distraction. Here is his resignation letter in full:
Dear prime minister,
As you know, there is an ongoing complaints process concerning text messages I sent to a colleague. I am complying with this process and have apologised to the recipient for those messages.
Since then, there have been other allegations made about my past conduct. I refute the characterisation of these claims, but I recognise these are becoming a distraction for the good work this government is doing.
I have therefore decided to step back from government so that I can comply fully with the complaints process that is under way and clear my name of any wrongdoing.
It is with real sadness that I tender my resignation, but I want to take this opportunity to offer my full and total support from the back benches. I am incredibly proud to have worked with you in government over the last few years and during the campaign.
Yours ever, 
Gavin Williamson
In response Prime Minister Rishi Sunak wrote:
