The health secretary, Jeremy Hunt, has said he will consider introducing new laws to limit the amount of sugar, salt and fat in processed foods to curb childhood obesity but said he wanted to give supermarkets and manufacturers a chance to get their "house in order" before resorting to legislation.

The comments come after his Labour counterpart, Andy Burnham, announced a consultation on capping sugar and fat levels in food targeted at children. Hunt criticised the former health secretary for failing to tackle the problem while he was in power, and said Labour had left the nation with the highest childhood obesity rate in Europe.
