The Sun (United Kingdom)
The Sun switched support to the Labour party on 18 March 1997, six weeks before the General Election victory which saw the New Labour leader Tony Blair become Prime Minister with a large parliamentary majority, despite the paper having attacked Blair and New Labour up to a month earlier. Its front page headline read THE SUN BACKS BLAIR and its front page editorial made clear that while it still opposed some New Labour policies, such as the Minimum Wage and Devolution, it believed Blair to be "the breath of fresh air this great country needs". John Major's Conservatives, it said, were "tired, divided and rudderless". Blair, who had radically altered his party's image and policies, noting the influence the paper could have over its readers' political thinking, had courted it (and Murdoch) for some time by granting exclusive interviews and writing columns.

Q: Who greatly changed the image of the Labour party?
