Party conference.

But the dramatic political weather is being set elsewhere.

In a landmark decision, the UK Supreme Court

has ruled that Boris Johnson's decision

to shut down Parliament for five weeks was unlawful.

The court is bound to conclude, therefore,

that the decision to advise Her Majesty to prorogue Parliament

was unlawful because it had the effect of frustrating

or preventing the ability of Parliament

to carry out its Constitutional functions

without reasonable justification.

Be in no doubt, this is a huge decision.

The Supreme Court ruled on two accounts.

First the prorogation is judiciable it is something

that judges will have a say on.

And second of all, that Boris Johnson misled the Queen when

he said that he wanted to shutdown Parliament

for a new legislative agenda.

In fact, it was to stymie Brexit debate.

What happens now?

Well, Speaker John Bercow has said the Parliament

will return immediately.

Although there's a slight snark in the fact

the prime minister is in New York,

addressing the UN General Assembly.

It's therefore likely his deputy,

the Foreign Secretary Dominic Raab will step in

and Parliament will resume very shortly.

But ultimately, what does this mean for Brexit?

Well, the fact is this Parliament

has ruled out every form of Brexit.

It's ruled out a soft Brexit, a hard Brexit, a no-deal Brexit,

no Brexit at all, a second referendum,

and a general election.

So the fact the MPs are now going to return fundamentally

doesn't change anything.

But MPs are likely to scrutinise Mr Johnson's government

further, and try and get a hold of some

of those crucial documents about Brexit.

But ultimately, the Supreme Court's decision

is going to further now the Parliament versus the people.

Mr Johnson sees as his aim to say

that he will deliver Brexit, come what may,

do or die, by October the 31st.

But now the judges have got in his way of his plans,

he's likely to talk up that rhetoric at the Conservative

Party Conference next week.

Forget the people versus Parliament.

It's going to be the people, versus Parliament,

versus the judges.

Hold on tight because this is a landmark moment

in British political history.
