“Investment into social enterprises can play an important role in our long-term economic plan as well as in addressing the toughest social issues. I congratulate Santander, Big Society Capital and the Social Investment Business in developing this fund, and would hope to see other High Street banks following their lead."

George Osborne, then Chancellor of the Exchequer speaking about the launch of a fund we invested in - the Third Sector Loan Fund.
