2012 Rotherham by-election

On 29 November 2012, a by-election was held for the UK House of Commons constituency of Rotherham. The by-election was caused by the resignation of its Member of Parliament Denis MacShane after the House of Commons Standards and Privileges Committee found that he had submitted 19 false invoices "plainly intended to deceive" the parliamentary expenses authority, an issue dating back to 2009 and a wider parliamentary expenses scandal in the UK. MacShane accepted the office of Chiltern Hundreds on 5 November 2012, formally vacating his seat. The election took place on 29 November 2012, at the same time as by-elections in Croydon North and Middlesbrough which were caused by the deaths of the sitting MPs.
