Class is no longer the dividing line in British politics that it once was, with Theresa May's Conservatives winning over the working class from Jeremy Corbyn.

In the 1992 General Election, things were simple. The Tories were seen as the party of the middle class while Labour could rely on the working class vote.

Back then the Conservatives led Labour among ABC1 (middle class) voters by around 30 points, while Labour was leading among C2DE (working class) voters by around 10 percentage points.

But today, the Tories lead among all groups of voters, with a massive surge in support among the working class for Theresa May.

Polling by YouGov shows that, as the 2017 General Election campaign beings, the Conservatives hold a 22 per cent lead among middle class voters and a 17 per cent lead among the working class.
