Comparative Political Studies

The combination of parliamentary government and plurality elections in the British House of Commons is often assumed to produce highly cohesive par-liamentary parties. However, the number and magnitude of backbench revolts against the governing party in the British Parliament has increased since the 1960s. The contention of this article is that particular forms of rebellion against the government are the norm rather than the exception in Britain. The reason, the authors contend, is that members of Parliament (MPs) who have been refused ministerial promotion or who are ex-ministers cannot be con-trolled by the promise of ministerial office and are hence free to vote against the government if they have variant policy preferences from the cabinet. This idea is confirmed in an analysis of Labour MPs ’ voting behavior in the 2001-2005 House of Commons
