Labour MP Chris Leslie has lost a vote of no confidence among members of his constituency party in Nottingham East.
The former shadow chancellor is the latest of a number of vocal critics of party leader Jeremy Corbyn to face such votes.
The result carries no official weight but recent changes to party rules make it easier to remove sitting MPs.
Mr Leslie and supporters boycotted the meeting, saying he had been unfairly targeted.
Labour’s Joan Ryan and Gavin Shuker lose no-confidence votes
Two Labour MPs who lost no-confidence votes among local party members have told constituents they will not quit.
Former minister Joan Ryan, MP for Enfield North, blamed the 94-92 vote defeat on “Trots, Stalinists, Communists and assorted hard-left”.
Luton South MP Gavin Shuker said he was “sorry a handful of people” wanted to overturn his 2017 win.
Both are among MPs to have criticised Jeremy Corbyn and faced no confidence votes in their local parties.
Others include Frank Field, who quit the parliamentary party last week citing the handling of the anti-Semitism row and bullying in local constituency parties, Kate Hoey, who has voted with the government on Brexit, and another Brexit-backing Labour MP Graham Stringer, who won his no confidence vote.
