Liane den Haan
She was a member of 50+ from August 2020 to May 2021 and leaded the party into the 2021 Dutch general election in March 2021. 50+ gained one seat, so she has been both parliamentary group leader and an MP since March 2021. Because of serious disagreements with the party executive committee, she left 50+ on 6 May 2021 and continues as an independent MP.
