Boris Johnson is stepping down as Conservative Party leader and will remain Prime Minister until a new leader is appointed

Hello Fabien, following the declaration that Boris Johnson has just made, we can answer that no, not immediately in any case. In the UK, the Prime Minister is automatically the leader of the party that has won the majority in the House of Commons. Thus Boris Johnson, leader of the Conservatives, who won an overwhelming majority of MPs in the 2019 elections. Today, he has just resigned as leader of the Conservative Party (Tories). He will be replaced by the next party leader without voters having to decide. The race to succeed him has already begun between many former ministers. The party should appoint a “short list” of two candidates, probably by July 21, the date of the end of the parliamentary session. The party might then decide between them by the beginning of September. Indicative, this calendar must be specified in the next few days.
