Leon, the healthy-eating fast food chain, is to double its number of outlets from 12 to 24 by the end of next year.
The expansion of the group, which is headed by Henry Dimbleby and John Vincent, will be funded by a £2m debt facility from Barclays, according to The Sunday Telegraph.
Leon currently has 10 restaurants in London and two outside at Heathrow Terminal 3 and Bluewater Shopping Centre. The new finance will help the group grow further beyond the capital, with sites already secured at Heathrow Terminal 2 and in the Eurotunnel terminal building in Folkestone.
There are also plans to expand the brand overseas, with a specific focus on the USA.
Earlier this year, Dimbleby and Vincent put forward their proposals for healthy eating in schools to the Department of Education in their commissioned School Food Plan.
