Azzurri Group is to close all Ask, Zizzi and Coco di Mama restaurants from today, CEO Steve Holmes has announced.

He said the decision was taken with the “deepest regret”, and came in light of government advice, and to protect its customers and teams.

The group will offer delivery from some sites which already offer this service. The announcement represents one of the biggest mass closures yet, with more than 250 sites to close.

Holmes said: “For many of our people, this will mean not working until we can safely reopen our sites and this has been the hardest part of our decision. We are incredibly proud of our teams, want to look after them in the best way that we can and will provide all of the support possible during this difficult period.”
