"It is absolutely fantastic to have someone of Raymond's calibre spearheading our drive to help the food industry wake up to the power of apprenticeships.
"From restaurants and bars to shops and suppliers, the capital's food industry is a booming trade that has huge potential to give thousands of young Londoners their first big break on the career ladder.
"With 100,000 apprenticeships now under our belt I believe this vibrant sector of our economy can play an increasingly important role in helping to swell that number even further."
