In the United Kingdom, both the governing Labour Party and the official opposition Conservative Party were in favour of the invasion. The Liberal Democrats insisted on a U.N. resolution; they opposed the war as a result. Outside parliament, anti-war sentiment was more widespread: the February 15, 2003 protest in London attracted between 750,000 and 2,000,000 supporters from various walks of life. Prominent politicians and other individuals expressing anti-war views included: Ken Clarke Charles Kennedy, Menzies Campbell, Tony Benn, George Galloway, Chris Martin, Damon Albarn, Ms. Dynamite, and Bianca Jagger.
