Voters won’t be able to complain when they head for the ballot box that politicians are all the same. Jeremy Corbyn’s manifesto marks a decisive departure from the consensus that parties propose higher taxes and more state intervention at their electoral peril. He is unrepentant about declaring that big business and the highest earners should dig deeper to improve public services which lag behind their European counterparts. Accusations that Labour is planning a ‘tax bombshell’ have proved fatal to its prospects in repeated elections and past leaders have bent over backwards to counter that charge. The challenge facing Mr Corbyn now is to hammer home his message that 95 per cent of the population would be unaffected by the proposed tax hikes. Opposition to austerity The current Labour leadership is also departing from the general acceptance in the political class that continuing to squeeze the public finances is essential for building recovery from the 2007-08 financial crisis. Ed Miliband and his shadow Chancellor Ed Balls did not disagree with the principle of the Cameron government’s austerity measures, only with the rate at which the screw was being tightened. But Mr Corbyn and John McDonnell take the view that austerity is not only causing human misery but also hobbling Britain’s economic prospects.
