Britain's Corbyn says his campaign 'changed politics'

The head of Britain's Labour Party, Jeremy Corbyn, today said the country's political landscape had been upended in a general election forecast to result in a hung parliament.
"Whatever the final result, our positive campaign has changed politics for the better," Corbyn said in a tweet.
An exit poll predicted unexpected gains for Labour in Thursday's vote, causing Prime Minister Theresa May to lose her overall majority.
