Worth noting it's extremely difficult to get an early election unless the Prime Minister wants it. The Tories could switch leaders, change Brexit plans, or even slowly head towards no-deal all without anyone pulling the pin on the Election.
You not only need a vote of no-confidence in the Government, but you then have to wait 14 days for no new government to emerge. Basically either the Pro-Remain Tories (about 5-10 MP) or the Hard Brexiters (40 odd MPs) have to decide that Prime Minister Corbyn is worth the risk
