Mr Cameron said 2012 “must be the year we go for it” and promised his Government would do everything it takes to get Britain up to strength.

Cameras, TV channels and the eyes of the world will be on Britain for two extraordinary events this year.

There will be three days of celebrations from 2 June for the Queen’s Diamond Jubilee, commemorating her 60 years on the throne.

Then, from 27 July to 12 August, London hosts the 2012 Olympic Games, followed by the Paralympics from 29 August to 9 September.

Mr Cameron said the events gave Britain the chance “to feel pride in who we are and what – even in these trying times – we can achieve.”

When speaking about “trying times”, the Prime Minister was talking about the money problems the UK has been having, along with many other countries.

This means that many people are worried about jobs and paying bills.

Mr Cameron said: “I know much needs to change. We’ve got to do more to bring our economy back to health.

“I know how difficult it will be to get through this. But I also know that we will.”
