Relations between Matt Hancock and Lindsay Hoyle have taken another turn for the worse after the Health Secretary locked down the Speaker's constituency without telling Parliament first.
Sir Lindsay is understood to have been angered that the plans to impose Covid-19 restrictions in Lancashire - which includes his Chorley constituency - were not set out by Mr Hancock in the Commons on Thursday.
One source said the Speaker was frustrated by the latest apparent snub from Mr Hancock, who has agreed to explain his reasons to MPs in the House of Commons for the lockdown on Monday.
A friend of Sir Lindsay said: "There are a lot of upset MPs in Lancashire. He could have warned Parliament. The House should be told first."
A friend of Mr Hancock said that there had been no formal decision when Mr Hancock gave his statement to MPs at 11am on Thursday.
The decision to bring in restrictions in Lancashire, Merseyside, parts of the Midlands and West Yorkshire was announced at midday on Friday although local MPs are understood to have been briefed earlier. Nearly 4.7 million people will be affected by the new lockdown rules.
The decision was only "collectively signed off" later that same day. The friend added: "We can’t announce decisions in Parliament that haven’t been agreed."
Sir Lindsay has often clashed with Mr Hancock in the House and has recently criticised him for announcing lockdown measures before telling the House of Commons.
Last week he demanded an apology today from Mr Hancock for "ignoring" MPs when unveiling the rule of six lockdown plans, accusing him of "running this chamber ragged".
Sir Lindsay also told of his anger over the issues people are facing booking coronavirus tests in Lancashire, writing on Twitter that it was "unacceptable" that his constituents cannot book a test.
He said: “I am receiving numerous complaints from residents unable to book a test after displaying Covid symptoms. This is completely unacceptable and totally undermines track and trace so I have raised my concerns with Ministers to push for action to be taken as a matter of urgency.”
In May Sir Lindsay threatened to eject Mr Hancock from the Chamber after scolding him for heckling Labour leader Sir Keir Starmer during Prime Minister's Questions.
