proposed a series of businesslike initiatives to free up sites for private development, to 6 Sep 2012 : Column 378 ut substantial guarantees and resources behind social housing, and to revive a sector that was destroyed in the false bubble created by the hon. Gentleman's Government. T2. [119418] Andrew Selous (South West Bedfordshire) (Con): How much does the UK earn from overseas students, and what assessment has the Minister for Universities and Science made of the potential for further export growth from that sector? Mr Willetts: We estimate that overseas students in higher education bring 8 billion to the British economy, which shows what a major export industry it is. We can be very proud of the success of our higher education sector, and that is why Britain has no limit on the number of suitably qualified overseas students who can come here to study. T3. [119419] Mr William Bain (Glasgow North East) (Lab): This morning the OECD predicted that the British economy will shrink by 0.7% this year. When will the Secretary of State get on and set up a proper British investment bank, and follow the example of institutions in Germany and Brazil that between them invested nearly 100 billion last year? Vince Cable: The hon. Gentleman is being a little churlish in not even acknowledging that on Sunday, the Chancellor made it clear that we wished to proceed with a business bank. We are discussing the range of its activities and the resources that will be available.
