I do think there will be an early election, later this year after the election of a new Conservative leader - they won't want to repeat the mistake that Gordon Brown made in not seeking an electoral mandate as PM. Of course it will require a 2/3rds majority of the House of Commons first.
Given that it appears that the majority of Labour's core vote voted "Leave" I think they'd find it extremely difficult to do what you are suggesting.
Too early to say what the outcome may be, and it depends upon who the Tories elect as PM but paradoxically I think they've a greater chance of being elected under a "no revoke" banner than Labour.
A national coalition Government committed to "no revoke" created by a pro-European alliance of Labour, leftish Tories, PC, Northern Ireland members and the SNP might be the best route.
The fixed term parliament act now makes it much more difficult to call an election.
There are three ways around this but none are easy.
Firstly the act transfers authority for dissolution to Parliament but sets a very high threshold of two thirds of all MPs. This in effect means all the Government side and about a hundred opposition MP's.
Almost by definition if indications or polls showed it a good time for the Conservatives to call an early election, it wouldn't be such a good time for the opposition parties and so achieving 75% by agreement from both sides of the house is not easy.
The second way is by a vote of no confidence in the Government but then this too would be fraught with difficulty, as that wouldn't be a way a Government would choose to go into an election and as they have a majority would be unlikely to be carried anyway.
The third and most likely way is by passing legislation to amend the act itself, but this would then have to pass through both houses and getting it through the Lord's if an early election was thought to benefit the Government would not be easy.
An early election is being talked about as very likely, i think it's far from that.
