Bob Diamond claimed institutes based in the nation will become much more highly valued in the near future and heaped praise on the government with regards to its stance on economic growth.

Mr Diamond observed the UK does not face similar challenges to those seen across Europe, adding: "It's ahead of many others in reducing public debt. It's working hard to pass the mantle of growth from the public to the private sector."
There is also now greater certainty regarding regulation in the UK, the Barclays chief - which has more than 300 years of history - added.
