British Prime Minister Gordon Brown has said America will lead the world out of recession, but he called on other countries to do more to revive their economies. In an impassioned speech to Congress he said lessons must be learned from the crisis, but that protectionism was not the answer.“So should we succumb to a race to the bottom and a protectionism that history tells us that, in the end, protects no one? No. We should have the confidence, America and Britain most of all, that we can seize the opportunities ahead and make the future work for us,” he said. He also called on the US to take advantage of a huge swell of goodwill towards America from Europe after President Obama’s election. And he said Iran would be welcomed back into the international community if it suspended its nuclear programme.
