general elections in decades.

And it's not just Brexit at stake.

Whoever gets the keys to Downing Street

has a radically different vision for the country's economy,

public services, and the future shape of the UK union.

So why are we having this election?

In a word.

Brexit.

Let's get Brexit done and unleash the potential

of the whole United Kingdom.

The whole point of this general election

is to break the Brexit deadlock in parliament,

but it's a huge gamble for Boris Johnson, the prime minister

and leader of the Conservative party.

He needs to come back to parliament with a majority

in order to deliver the Brexit deal that he negotiated

with Brussels earlier this year.

If he doesn't, pro-Remain parties here in parliament

could move to try and stop Brexit altogether.

That's the Labour party, right?

Well, not quite.

Jeremy Corbyn's opposition party haven't committed yet

to Leave or Remain.

But they have promised a second referendum

if they come to power.

We will secure a sensible deal that protects manufacturing

and the Good Friday Agreement, and then

put it to a public vote alongside the option

of remaining in the EU.

The Liberal Democrats under the leadership of Jo Swinson

have vowed to revoke Article 50 and cancel Brexit altogether.

But if they don't win the election, which

is highly likely, they are expected to also campaign

for a second referendum.

So if you want to stop Boris Johnson and stop Brexit,

vote Liberal Democrat.

The Scottish National party under Nicola Sturgeon,

the Welsh party Plaid Cymru; and the Greens are all in favour

of a second referendum.

The two major political parties have dramatically different

visions for the UK economy.

Labour are keen to get the conversation away from Brexit

and talk about what is one of the most radical leftwing

manifestos the party has ever seen.

Labour's manifesto is a manifesto for hope.

They're promising to increase tax and spending

and also nationalise some of the key industries in the UK,

such as Royal Mail, the railways, and even broadband.

The Tories are also hoping to take advantage of low interest

rates and borrow more to invest in infrastructure.

But instead of going after businesses,

they're promising tax breaks for everyday workers.

But really, they're keen to keep the conversation

on the issue of Brexit with a promise to get it done.

There you go.

Get it done, Boris.

We will.

The UK National Health Service, which

offers free universal care for everyone,

is always a major issue in any general election campaign.

Our NHS is not for sale.

But this winter the NHS is coming under particular strain,

and all the major political parties

are promising to spend more money.

So what happens if no party comes back with a majority?

Well, we'll be left with something

called a hung parliament.

In that circumstance, the party with the most number of seats

would have an opportunity to reach out to the smaller

parties and try and form a coalition or a confidence

and supply agreement.

They could also try and form a minority government.

The problem is the Liberal Democrats

are so far ruling out using their votes

to put either Jeremy Corbyn or Boris

Johnson into Downing Street.

Because we deserve better than what

is on offer from the two tired old parties.

And the Scottish National party have said the price

for them supporting any minority or coalition government is

the promise of a second independent Scottish referendum

within the next couple of years.

Now, what the smaller parties are saying now

and what they would actually do in the event of a hung

parliament could be very different.

But if no one can come to any sort of agreement,

or if no one can rule through a minority government,

we might be forced into another general election.
