No, Downing Street, PM, or whatever term you want to try to use for the head of the government, cannot prevent a sitting candidate from standing again. That is entirely the prerogative of the local Conservative party officers and members (I can speak from personal knowledge of how both major parties work in this respect, and in the distant past was a party officer in my local constituency). If the officers were to de-select the MP and then see the local membership support the MP, you would see a new set of officers and selection committee members appointed. If it were down to leaders of the parties who stood, you would have seen people like Bercow and Skinner vanish far earlier than they did. The local party may well follow a 'hint' from people higher up, but if the MP is popular with his local members and electorate they will keep him - this is why certain 'maverick' MP's do so much constituency work! It is very hard to remove a sitting MP with his local party onside as you then need to prove he has done something to bring the party into disrepute (an no, not agreeing on the party line did not count then) by some form of criminal conduct. Many officers in a local party to me wanted to replace the local MP in the 1990s, he is still there today as he has massive support from the local membership, though a lot less from the leadership of the party where a long-standing personal dislike exists.ljadw wrote: ↑14 Jan 2022 20:28Oh yes : Downing Street 10 (= the PM ) can prevent sitting MPs from being again candidate ,as the nomination of candidate depends on a very small number of people ,as the local party leader,who would do a lot of things for a knighthood or a peerage.And the patience of the party leaders with Churchill was exhausted .
And,he was not deselected because there was no election in November because of the war .
Also, Churchill and Chamberlain happened to be relatively friendly both before the war and after it started, as shown by Churchill's own words about keeping Chamberlain in govt after he resigned as PM and at how devastated Churchill was by his death.
