Later today (UK time), the House of Commons will begin debating, over more than 10 hours, UK participation in airstrikes against Islamic State in Syria. The issue has badly split the Labour Party and (again) demonstrated the apparently huge gulf between leader Jeremy Corbyn and much of his own cabinet and parliamentary party. The Tories aren't without their own divisions -- the Tory-chaired foreign affairs select committee voted that the Cameron government had not “adequately addressed concerns” about military intervention -- but in the free vote Corbyn has been forced to allow, his own shadow foreign secretary Hilary Benn and his deputy Tom Watson will both vote in support of airstrikes while Corbyn is bitterly opposed.
