A review of labelling of halal meat will be conducted if the industry fails to deliver more transparency within the next few months, Downing Street has said.
The Prime Minister has said that the issue is a matter between retailers and restaurants and their customers.
He told ITV West Country: "If you are going into a restaurant you assume that it is not halal meat unless you are told otherwise. Do we need a national labelling scheme? I would rather hope not. I would rather hope it could be dealt with by the restaurants and businesses.
