John Bercow has told friends he intends to stand down as Commons Speaker next summer, the BBC understands.
The news comes after a damning report on the failure of high level figures in Parliament to deal adequately with bullying of staff at Westminster.
The report, which condemned a culture in which abusive behaviour was "tolerated and covered up", prompted calls for Mr Bercow to quit right now.
Speaking in the Commons, Former Tory cabinet minister Maria Miller told Mr Bercow a "complete change in leadership" was needed at the top of the parliamentary authorities "including you".
