Where do UK political parties stand in the Brexit election?

It's dubbed the Brexit election, but there'll be more at stake when Britons head to the polls on December 12.

UK parties are promising big spending and pledges that could fundamentally transform the United Kingdom.

So, here's where they stand:

Prime Minister Boris Johnson is seeking a mandate to "Get Brexit Done."

(SOUNDBITE) (English) BRITISH PRIME MINISTER BORIS JOHNSON, SAYING:

"Just nine more seats, just nine more seats, and we can deliver Brexit in January and get parliament working for you and unleash the potential of the whole country."

His traditionally pro-business Conservatives are yet to publish a manifesto, but they argue they're best placed to grow the economy and say they'll spend an extra £20 billion a year on hospitals, schools, and infrastructure.

Johnson also rejects the opposition Labour Party's allegation that he plans to "sell-off" Britain's beloved National Health Service in a post-Brexit trade deal with the United States.

Labour is also planning to spend big - £55 billion a year - on what veteran socialist leader Jeremy Corbyn calls the most ambitious and radical plan in decades.

(SOUNDBITE) (English) BRITAIN'S LABOUR PARTY LEADER, JEREMY CORBYN, SAYING:

"We will deliver real change for the many, not the few. That's what this manifesto is all about."

Labour's pledges include the widespread nationalization of utilities and a Green Industrial Revolution to create one million jobs while tackling the climate crisis.

The Conservatives, however, have tried to exploit a perceived lack of clarity over Corbyn's position on Brexit.

He says he will negotiate a better deal with the EU and then put it to the public in a referendum, with remaining in the EU an option.

But there're no doubts over the Liberal Democrats position.

They've said they will cancel Brexit generating a "remain bonus" of £50 billion a year that they'd invest in public services.

(SOUNDBITE) (English) LIBERAL DEMOCRATS LEADER, JO SWINSON, SAYING:

"Because we deserve better than what is on offer from the two tired old parties, from the two men who only know how to rehash ideas from the past."

The Brexit Party is not publishing a manifesto but as you may have guessed, they're very pro-Brexit.

Party leader Nigel Farage is calling for a "clean-break" and has said Johnson's deal is not a "proper" Brexit.

(SOUNDBITE) (English) BREXIT PARTY LEADER, NIGEL FARAGE, SAYING:

"Boris' great new deal is 95 percent the same as Mrs. May's bad old treaty."

Most polls have put the Conservatives in front though analysts warn the issue of Brexit has torn traditional political allegiances apart and made the outcome unpredictable.
