Cains – the Liverpool-based brewer and pub operator – could face closure over an unpaid tax bill, it was revealed yesterday. The BBC said last night that HM Revenue and Customs had filed a petition for the company to be wound up because of money it claims they owe. Cains' chief executive Sudarghara Dusanj told BBC News : "It is a very serious situation. We are in talks with our bank to try to borrow the money." The reports of Cains' unpaid tax followed the announcement that the operator and brewer had reported a “significant loss” of £4.5m for the six month period to 28 April. Cains had previously reported a £2.8m loss for the fourteen months to 28 October 2007 following its reverse takeover of Honeycombe Leisure. The Liverpool brewery was rescued from collapse in 2002 by the Dusanj brothers.
