This series of publications contains data on various subjects relating to Parliament and Government. Topics include legislation, MPs, select committees, debates, divisions and Parliamentary procedure.
Due to the difficulties in compiling a comprehensive list of all floor-crossings, whip withdrawals and whip resignations, this list cannot be guaranteed to be definitive.
We are always happy to hear of any additions or amendments to the list. Please email papers@parliament.uk with any comments.
We also welcome suggestions for new lists.
