Labour MP Frank Roy has been censured by the Commons committee on standards and privileges for betting on the outcome of the Speaker election.

The Motherwell and Wishaw MP won £4,000 after betting £200 that Michael Martin would succeed Betty Boothroyd with at odds of 20-1.

The committee backed parliamentary commissioner Elizabeth Filkin to uphold a complaint by a member of the public. It advised no further action to be taken but reprimanded Roy in a strongly-worded statement. "Betting by Members on the outcome of any parliamentary business brings discredit on the House."
