David Cameron has hailed a new £350 million construction project in the heart of London as proof that the coalition's crackdown on planning red tape is working.

The Prime Minister said the go-ahead for two major buildings in Victoria would support 2,500 jobs and help get the economy moving.

The announcement came as the Government introduced the Growth and Infrastructure Bill to Parliament.

Ministers claim the package will unlock billions of pounds worth of investment in energy schemes, by easing bureaucratic burdens on developers and employers.
