The Sun (United Kingdom):

Despite being a persistent critic of some of the government's policies, the paper supported Labour in both subsequent elections the party won. For the 2005 general election, The Sun backed Blair and Labour for a third consecutive election win and vowed to give him "one last chance" to fulfil his promises, despite berating him for several weaknesses including a failure to control immigration. However, it did speak of its hope that the Conservatives (led by Michael Howard) would one day be fit for a return to government. This election (Blair had declared it would be his last as prime minister) resulted in Labour's third successive win but with a much reduced majority.
