UK Prime Minister Gordon Brown (pictured above, looking both evangelical and nauseatingly mock-sincere) will declare this week that Britain is emerging from recession and that the economy is on the “road towards recovery”. The PM will deliver this extraordinarily upbeat assessment (a.k.a. bullshit) in a speech to Trades Union leaders exactly one year on from the start of the credit crunch and the worldwide financial crisis. His claims will come as he faces a fresh challenge to his authority from the leader of Britain’s biggest union, who yesterday warned Brown that he must ”get rid of” Business Secretary Peter Mandelson and Foreign Secretary David Miliband or face “slaughter” at the general election.
