Theresa May has called a snap election and placed the biggest bet of her career?

Perhaps it was something in the mountain air of Snowdonia that helped clear Theresa May's mind to make the boldest decision yet of her short premiership, suggests  David Hughes.

The British Prime Minister used the day Parliament returned from the Easter recess - part of which she spent walking in North Wales - to say she had "recently and reluctantly" concluded that she would call a snap general election.

The decision to call an election marked a screeching U-turn after repeated denials that she would go to the country at a time when the UK's future relationship with the European Union was up for negotiation.
