The MP for Nottingham East, Chris Leslie, has lost a vote of no confidence.
The former shadow chancellor was a vocal critics of party leader Jeremy Corbyn and fellow Labour MPs say he is now the latest victim of a "purge".
Similar action has been taken against Labour Friends of Israel chairwoman Joan Ryan, Luton South MP Gavin Shuker and the Labour Brexiteers Kate Hoey and Frank Field.
Mr Leslie has been MP for Nottingham East since 2010 but on Friday night (28th September) he became the latest parliamentarian to be censured.
"If the party pushes away people like me on the centre left for voicing different opinions to the leadership, then that says more about the direction of Labour than it does about me. I'm not going to stop speaking up for all my constituents when there are so many massively important challenges, especially the threat of a disastrous Brexit."
Those MPs targeted by local party votes have either been critics of Mr Corbyn on subjects including anti-Semitism, or hardline Brexiteers who voted with the Tories on key legislation.
The result carries no official weight but recent changes to party rules make it easier to remove sitting MPs.
