t that Mr Blair was apologetic. He described how, during his decade in Downing Street, the challenges facing government had shifted from the essentially domestic—managing the economy, rebuilding neglected public services and fighting poverty—to more threatening and intractable global concerns. Those include not just terrorism but mass immigration, looming energy shortages and climate change. Above all, he wanted to remind his party how it had won three successive elections and could win a fourth by an unceasing focus on people s hopes and fears. “The core vote of this party today�? he said, “is not the heartlands, the inner city, not any sectional interest or lobby. Our core vote is the country.�? New Labour, he boasted, had created a coalition by reconciling compassion with aspiration. Now the task was to reconcile liberty with security. The only legacy that had ever mattered to him, insisted Mr Blair, was winning a fourth election victory. If Mr Blair thinks he knows how Labour can win a fourth term, he is a good deal less certain about who is capable of delivering it. In a concerted effort to patch things up following the recent unrest, Mr Blair and Gordon Brown each paid public tribute to the other this week, while acknowledging how fraught their relationship has often been. According to Mr Blair, Gordon was a remarkable man without whom those three election victories could not have been won.
