London (CNN) Boris Johnson promised a new vote on his Brexit deal by Christmas and a raft of funding pledges if the Conservatives win Britain's general election, as he launched the party's manifesto launch on Sunday.

The Prime Minister said a quick lawmakers' vote on his withdrawal agreement, which was on the cusp of progressing through the Parliament before Johnson pulled it in favor of an election , would open a "new chapter" in Britain's history and allow the country to leave the European Union by its current deadline of January 31.

"Do you want to wake up on Friday the 13th of December and find a nightmare on Downing Street? A Corbyn/Sturgeon coalition of chaos," Johnson asked a crowd in the West Midlands during the launch event. "Let's go for sensible, moderate, but tax-cutting, one-nation Conservative Government and take this country forwards."

He criticized the Labour leader Jeremy Corbyn for pledging to stay neutral during a second referendum on Brexit, and frequently repeated his mantra to "get Brexit done" -- but the opposition party warned his plan entails years of further trade negotiations with the EU and the United States.

Johnson also announced a "triple lock" on income tax, national insurance and VAT rates, alongside pledges for 20,000 new police officers and 50,000 extra nurses, an extra £1 billion for social care and an Australian-style points based immigration system.
