Good morning, I'm Naz with Thursday's Newsround!

First up, a new day and a new Prime Minister.

It's the first full day in the job for Theresa May.

She took over from David Cameron last night and says she wants

to build a UK for everyone. Here's what happened.

We will make Britain a country that works not for a privileged few

That was the moment the new Prime Minister walked

into her new home, 10 Downing Street.

Mrs May has taken over as Prime Minister.

The last person in charge was David Cameron.

He decided to resign after the big vote when the UK decided

He is one of the youngest prime ministers this country has ever had.

After six years and 62 days in Downing Street,

and when you were probably having your tea, David Cameron

said his final words as the leader of the UK.

It has been the greatest honour of my life to serve our country

as Prime Minister over the last six years.

Now, whenever there is a change of Prime Minister or Government,

the person leaving and the one taking over have to

David Cameron, his wife and children went to Buckingham Palace to see her

merger to and officially stepped down from his job. Theresa May was

next to see the Queen and that was her big moment. She became the new

Conservative Prime Minister. Mrs May left the palace and returned to ten

Downing St, where she started picking her top team. One is Boris

Johnson, who many thought would be the next Prime Minister. Now she is

there, she will start work as only the UK's second female Prime

Minister. Her biggest job? Sorting out how the UK weaves the European

Union. But don't worry about Larry, the Downing Street cat, he will be

staying right where he is. Next, something BIG is happening

beneath the streets of London. Deep underground the UK is buiilding

a giant new underground Here's CBBC's super scientific

reporter Fran Scott on what goes I'm right in the centre of London

at Farringdon station. And it might look like everything

is normal here but beneath my feet, the biggest building

project in Europe is going The massive project to build this

new train line for And in the summer of 2012,

while London was hosting the Olympics, massive

machines started digging. It has taken well over

20,000 workers, over 100 million hours of work,

and they've had to move millions of tonnes of mud

in the 42 kilometre route. The digging finally

finished right here, where the tunnelling

machine, called Tory, broke through to reach this -

what will become the new Farringdon Now, they're working on getting

seven new stations ready So, how do you go

from this... Chloe is one of many engineers

working to make that happen. So, an essential part of any railway

is the actual track. We're going to lay ours right

here where we are walking. So we won't be able to walk

here in the future? No - trains will be running

through this tunnel, picking up passengers and taking

them to their destinations. Chloe, this looks incredible.

What is it? This is a temporary shaft,

it won't be part of We use them during construction

to bring materials in and out You just crane them in?

Yes. That's brilliant! This is one of our escalator tunnels

here at Farringdon. What you can see now is the final

concrete lining being put on top of the orange

waterproofing. This will eventually be one

of the access points There are lots of parts that make

up a working station, but this one will not be ready

for us to use for another 2-3 years. Which is a good job because there

are still lots to do. Some people in Colorado in America

are used to seeing grizzly bears, but somehow, THIS bear

managed to lock itself in a car, despite not

breaking any windows... Don't worry, though,

the bear was unharmed. That's all from me, Newsround's back

right here in about half an hour.
