John Vincent on bouncing back after cutting branches, refreshing the menu, and staff learning from martial arts

John Vincent is going back to the future. Four years after selling Leon, the fast food chain named after his father and founded in 2004 with two friends, he has bought it back with hopes of reviving its fortunes.

Fast food chain Leon is planning to close restaurants and cut jobs, less than two months after it was bought back from Asda by its co-founder John Vincent.

The online card service Moonpig has reported a bump in sales thanks in part to its increased use of AI to help design cards, personalise customers’ messages and answer queries.

The company said sales rose 6.7% to £169m in the six months to 31 October and had remained strong in the weeks since then, largely as a result of increased orders and spend per order at its main Moonpig brand.
