Turkey's governing Justice and Development Party (AK Party) on Tuesday presented a bill to remove immunity from prosecution from nearly a quarter of lawmakers.
The proposal would amend the constitution with a temporary clause to remove protection from prosecution from 129 of the Grand National Assemblys 550 deputies.
The targeted lawmakers, who come from all four parliamentary parties, have had a total of 562 criminal proceedings lodged against them.
The bill, which was sent to the office of the parliamentary speaker, was signed by 316 AK Party lawmakers, including Prime Minister Ahmet Davutoglu.
The removal of immunity from prosecution has been on the political agenda for some time. The debate has previously centred on opposition lawmakers, particularly those from the HDP, predominantly pro-Kurdish Party.
If you committed a crime, you will pay for it, President Recep Tayyip Erdogan said on Monday.
