Jamie Oliver looks set to open a fifth branch of his Fifteen training-restaurant concept in Leeds next year, reports citylite.co.uk. There are already operations in London, Amsterdam, Cornwall and Melbourne.

And more Jamie news emerges in a major interview in The Independent. It seems that, to make his forthcoming high street chain dream a reality, he now really is prepared to ‘put his money where his mouth is’.

We were rather critical of Jamie in a former news item about his modest personal investment in the chain which is to bear his name (the first branch of which will open in Oxford in early-June). Such reservations, it seems, are now misplaced. After a tiff with the would-be investors, it seems this is now to be very much Jamie’s show. He says that “[the investment is] all my own money, with my house and everything thrown in as a collateral and just one very small shareholder, and that's my business partner who runs everything with me”.

And, if there were still any doubt, we are told the chain is “definitely the most important thing I'm going to be doing for the next five to 10 years”.
