Ahead of the opening, the Prince of Wales shone a light on young entrepreneurs helped by his trust when he visited a London shop stocked with their innovative products.

Charles toured Tomorrow's Store near the City of London where jewellery, clothing, homeware and stationery were on sale.

Charles also met people who have been taking part in the Arc programme run by the charity Business in the Community (BITC), which has the Prince as president.

Arc is BITC's flagship enterprise programme which began in 2011 and aims to connect social entrepreneurs in the Olympic host boroughs with expert support from companies like BP, Deloitte and Visa Europe.

The programme focuses on job creation and boosting social enterprise growth.

Later today Charles, president of the Prince's Initiative for Mature Enterprise, will host a reception to celebrate entrepreneurs who have benefited from the project, its supporters and volunteers.
