We sent Leah, along with Press Packers Arian and Nivar, to speak to the Prime Minister about climate change.
There was a lot of setting up to be done before interviewing one of the most important men in Britain!
The prime minister is going to the climate change conference in Copenhagen, and our team asked him how he thought it would go.
They also asked him about what he did to make his life greener.
The guys also put some tough questions to David Cameron - the head of the Conservative Party. They're also set to talk to Nick Clegg, head of the Liberal Democrats.
It's possible that David Cameron will be the next Prime Minister. So it's important to know what he thinks on the environment.
