Cameron promises to trigger new growth

David Cameron has promised to invest to ensure the UK's future economic growth, with an emphasis on entrepreneurs.

The Prime Minister told the CBI conference £30bn would be invested in transport projects over the next four years as part of a package to keep the UK recovery on track.

He said: "This is an incredible opportunity for Britain, for new start-ups to flourish, for innovations to drive growth and create jobs.

"To build that new dynamism in our economy, to create the growth, jobs and opportunities Britain needs, we've got to back the big businesses of tomorrow, not just the big businesses of today."
