Good morning, I'm Ayshah with all the top stories this Tuesday.

Keep watching for all of this.

Big news about Brexit.

Find out why this dog is going to school...

And the miraculous birth of this baby bat.

It's been over half a year since the people in the UK voted

in an historic referendum to leave a club of countries called

the European Union.

However, we haven't officially told the European Union that

we're going to leave.

This can only be done by triggering a law called Article 50.

So why hasn't it been done yet?

Here's our political guru, Chris Mason.

This is all about a decision being made here by the UK's Supreme Court.

It is the most important court in the land.

The 11 judges have to decide who should be in charge

of telling the European Union that we are leaving.

Officially, the process is called "triggering Article 50".

Once that has happened, the UK has got two years

to get it all arranged.

Some people think the decision should be made by those

who make our laws, MPs, in Parliament.

And the Scottish Parliament, the Welsh assembly and people

in Northern Ireland want their views to be heard too.

But the Prime Minister, Theresa May, thinks the Government shouldn't have

to ask permission to say goodbye.

We'll find out later this morning what they decide.

But whatever they say, it's the next big step

in what is a really important time for the future of this country.

And don't forget, there's loads more info about what leaving

the European Union could mean for the UK and how

it's going to happen.

and phrases everyone seems to be using!

To tennis and Britain women's number one Johanna Konta says she's done

everything she can to be ready for her first ever meeting

with 22-time Grand Slam winner Serena Williams

at the Australian Open quarter finals on Wednesday.

Konta has won 18 sets in a row and she says says

she's pretty excited.

She is one of the, I mean if not THE best player for us

to ever have in the game, so I think to play against someone

like that, who you also grew up watching, I think is another great

opportunity for me to take a really mega load of experience from.

Next up - this is Alice, she's 15 and has trouble seeing

but now her life has been transformed by Billy,

her very own guide dog.

Alice is one of the youngest people in the country

to be given a guide dog.

The pair go everywhere together, including school.

It's the new term and there's a new face at this high

school in Nottinghamshire.

A very furry one.

Billy the Labrador is just one of around 50 expert pets helping

to guide blind children or those who have problems with

therir sight in England.

I think it's good because I don't have to constantly have

people watching me. He gives me a bit more freedom.

In the past, guide dogs weren't paired with children

as they were thought to be too much of a responsibility

for a young person. But now, the rules have changed.

The amount of work you have to do with him and the

responsibility is overwhelming.

But if you put the work in, you get the results out of it.

These two have been together since October

and are getting on just fine.

Having Billy in school just allows her to gain that

independence, build resilience, confidence, and go

through her school life as every other child would.

The school had to create a quiet area for Billy to rest

in and somewhere for him to walk.

And he's been a big hit with the rest of the pupils too.

He's a bit of a poser.

They did say the novelty will wear off but everybody still loves him.

Zoo keepers at San Diego Safari Park are celebrating the miraculous

arrival of this baby fruit bat...

His mother had problems giving birth and staff needed to perform

an emergency operation to save him.

The surgery had never been done on a fruit bat before.

Thankfully, 12-day-old Rodrigues is now doing really well,

he's being hand-fed by staff at the zoo.

I have to show you this before I go, it's a bus that drives itself!

It's just been launched in France.

It will go between two train stations to start.

It can carry ten people at a time and uses sensors to figure

out its surroundings.

That's all from me, Newsround's back right here in about half an hour.
