Labour gains ground in England and Wales
Mrs. May held a snap election hoping to significantly increase the narrow parliamentary majority that her Conservative Party had won, under different leadership, in 2015.
Instead, the Labour Party performed much better than expected in Wales and in England, especially London. In Scotland, the Conservatives made gains, but so did Labour. A key outcome may be that in Northern Ireland, the Democratic Unionist Party, a potential ally of the Conservatives, gained seats.
Young voters turn out for Labour
There were doubts that younger voters would cast their ballots for the Labour leader, Jeremy Corbyn. But this year there was a spike in young people registering to vote — more than one million people under 25 applied — and turnout in constituencies with younger voters rose significantly, benefitting Labour.
Smaller parties see a decline
This election was a test of whether the pro- and anti-Europe fault line that runs through British society — which was exposed by the 52-48 result in the Brexit referendum last year — would further erode the power of the two main parties.
Recent elections in Britain have seen a decrease in the overall share of the vote going to the Conservative and Labour parties, but the results of this election suggest that the country is shifting back toward a two-party system.
