Defiant John Bercow signals he will stay on as Speaker amid pressure from MPs

A defiant John Bercow has signalled he intends to remain as Speaker, amid calls from MPs to debate his replacement.Leader of the House Andrea Leadsom said she did not think MPs would welcome a proposal from former Conservative minister James Duddridge to discuss what they want from a holder of the role before discussing a successor.Mr Duddridge told the Commons such a debate was needed because of Mr Bercow's original pledge to serve no more than nine years in the job.
