“I think our pubs are going to be full to capacity,” Emeny said. “Unfortunately we are still trading with a lot of restrictions. I have no doubt that we will sell out, but clearly if the restrictions had been lifted when the Prime Minister had originally said they would be we would have even more customers in.”
Dozens of nightclubs, still unable to operate normally because of Covid, have turned themselves into pubs for the night to accommodate fans who want to watch.

John Foster, of the CBI, said: “The success of the England football team has lifted spirits, made Neil Diamond the soundtrack to the summer, and provided a boost for firms selling beer, barbecues and bunting.
“Conversations will no doubt be taking place throughout England as employers and employees look to strike a sensible balance for Sunday’s final. Where possible, businesses will be looking to show flexibility and a bit of common sense to allow their teams to enjoy the occasion.”
