Father and son Kazem and Michael Najafi had previously owned Quiznos' UK licence and planned to open 500 outlets here.
Companies House now lists the firm as being overdue with its last accounts in the UK. A few UK franchise outlets remain, supplied directly from the USA. One remaining franchisee told British Baker that a new master franchisee for the UK would be appointed shortly.
