Renewing the Centre?

Have recent events – notably the election (and re-election) of Jeremy Corbyn as leader of the Labour party following the Conservative victory in the 2015 general election, and the 2016 vote to leave the EU leading to a ‘hard Brexit’ strategy from the Conservative government – revitalised British politics by breaking from the centrist politics of the preceding period? Was ‘centrism’ a problem that needed to be solved or is the problem that the main parties have vacated the centre ground of politics, creating an urgent need for the centre to be renewed? Is centrism the problem or the solution?
