Devon-based Tim Martin (64) founded pub chain Wetherspoons in 1979 and today owns 31.9pc of the business (worth €612m) which sells cheap beer and meals. The firm plans to open at least four new pubs here over the next four years.

The Belfast-born Brexit supporter and outspoken critic of the City has benefited handsomely over the past year, as the share price is up by 44pc. Pay and dividends netted him €5.17m last year, before tax.
