Sculptures made of sugar were put up in front of the Houses of Parliament in London on Tuesday to highlight the need for the public to reduce sugar intake.
A parliamentary Health Committee report published on Monday urged British Prime Minister David Cameron to take urgent action and support a call for a sugar tax to tackle child obesity.
Among other measures, it urges controls on promotion of "unhealthy food and drink". It also said there should be tougher controls on marketing and advertising of such food and drink, and that labels should show sugar content in teaspoons, among other measures.
Treatment for obesity costs Britain's state-run health service £5.1 billion (S$10.8 billion) every year.
