The Conservative Party , led by Michael Howard since late 2003 , campaigned on policies , such as immigration limits , improving poorly managed hospitals and reducing high crime rates , all under the slogan ' Are you thinking what we 're thinking ? ' . The Liberal Democrats , led by Charles Kennedy , were opposed to the Iraq War given there had been no second UN resolution , and collected votes from disenchanted Labour voters . Tony Blair was returned as Prime Minister , with Labour having 355 MPs but with a popular vote of 35.2 % , the lowest of any majority government in British history . In terms of votes they were only narrowly ahead of the Conservatives , but still had a comfortable lead in terms of seats . The Conservatives had 198 MPs , 32 more than they had previously , and won the popular vote in England , while still ending up with 91 fewer MPs in England than Labour . The Liberal Democrats saw their popular vote increase by 3.7 % and won the most seats for any third party since 1923 , with 62 MPs . Former Labour MP and anti-war activist George Galloway was elected as a member of the Commons under the Respect -- The Unity Coalition banner , and two single area party candidates were elected : Blaenau Gwent People 's Voice and Kidderminster Health Concern in Worcestershire . In Northern Ireland the Ulster Unionist Party , the more moderate of the main unionist parties , which had dominated Northern Ireland 's politics since the 1920s , was reduced from six MPs to one , with party leader David Trimble himself losing his seat . The more hardline Democratic Unionist Party became the largest Northern Irish party , with nine MPs . Following the election , Conservative leader Michael Howard resigned and was succeeded by David Cameron ; and in 2007 Blair resigned as Prime Minister and Labour leader to be replaced by Gordon Brown .
