Keir Starmer accused the Prime Minister of calling the vote after realising “she’s not going to be able to deliver the Brexit deal she’s been promising”.
He also bashed the Mrs May for attempting to “remove scrutiny and accountability” by calling for a stronger Tory majority in the House of Commons.
The Labour MP told BBC Radio 4’s World at One: “I am concerned because I think this is the realisation by Theresa May that she’s not going to be able to deliver the Brexit deal she’s been promising and is anxious that in 2019, things will not have gone in the way she has said they will go.”

Addressing whether he thought his party was being “obstructionist” in relation to Brexit, Mr Starmer blasted Mrs May for not being able to take criticism.
He said: “She has treated any questioning of what she is doing as frustration – I think that’s wrong.
“And one of my big concerns is that what she’s attempting to do is to remove any scrutiny and accountability over the next two years.

Keir Starmer said Jeremy Corbyn could "rise" to the challenge
“So we have this period in which the future of the UK in Europe, in the world, is in play and she wants to remove scrutiny and accountability and that lies beneath, I think, this snap decision just as much as the polls do.
“I think that’s a very dangerous place for us to be.”
When asked about Labour’s chances, despite falling behind in the polls, the politician admitted his party had a “huge challenge ahead”.
He said: “I think what’s important is that we define that challenge. This is not about the technical nature of any Article 50 deal.
“This is about the shape of Britain post-Brexit and I think on that territory, with the policies that we’ve got, that’s a battle we can rise to – but rise to it we must.”
