It is not down to effective leadership, but a return to two-party politicsby Peter Kellner / May 15, 2017 / Leave a comment
Much of the coverage of the weekend polls has concerned the rise in Labour’s support, to more than 30 per cent. In fact, their more important, potentially historic, message is that Theresa May is on course for the biggest mandate won by any prime minister for half a century. The latest polls give the Conservatives 48 per cent on average, up three points since the PM called the election. If the Tories hold their gains until 8th June, theirs will be the highest vote share won by any party since 1966.
Neither Margaret Thatcher nor Tony Blair won this level of support in their landslide victories. They both achieved their biggest wins with 44 per cent of the vote—Thatcher in 1983, Blair in 1997. May is on course to overtake them by four percentage points, equivalent to more than a million votes. We have to go back to Labour’s victory under Harold Wilson 51 years ago to match May’s current vote share.

That, however, was a close-run thing, with both Labour and the Tories winning more than 40 per cent of the vote. If the Tories’ curre…
