A year later, Smith suffers a fatal heart attack. Blair, encouraged by his wife Cherie (Elizabeth Berrington), decides to stand in the leadership contest. He later meets with Mandelson to tell him that he has received support from key Labour frontbenchers. Previously a supporter of Brown, Mandelson switches his allegiance to Blair. Brown is furious that Blair has gone back on what he perceives as having been an unwritten understanding between the two that Brown was the more likely candidate for the leadership, but Blair is incredulous – believing that the circumstances have changed enormously in the intervening years. Smith's funeral passes, and Blair's camp is sure that Brown will run. Charlie Whelan (Dexter Fletcher) and Ed Balls (Matt Blair) advise Brown that he will receive support from significant trade unions. Blair decides to arrange a meeting with Brown. At Granita, Blair tells Brown that he will run for the leadership, and in return offers Brown unprecedented power as his Chancellor, should they win the next election, also offering Brown sweeping control of social policy. Brown asks what Blair's plan is should Labour win a second term in office, and Blair responds that he would not make the same mistake as Margaret Thatcher and "go on too long," agreeing to offer his support to Brown as his successor. Brown agrees and Mandelson prepares a statement from him, but discards Brown's alterations. The leadership contest is won by Blair.
