Nicky Morgan has been appointed Culture Secretary by Boris Johnson so the position of chair of the Treasury Committee is becoming vacant.
The Speaker has said he hopes the election, which will be voted on by all MPs, will be held "in the second week of the September sitting".
Steve Baker, former Brexit Minister, has tweeted that he will stand "and I hope to engage colleagues across the House, not least through my work advancing cooperatives and justice in the financial system."
We've also spotted this tweet from Stephen Hammond. We will endeavour to bring others if we see them.
