A majority of people polled for a survey agree there should be a health-related tax on sugar-sweetened drinks to help reduce childhood obesity.

The survey, carried out for the Irish Heart Foundation, found that 52% of the public are in favour of the tax compared to 46% against.

87% of those polled in the Ipsos MRBI survey believe that sugar-sweetened drinks contribute to obesity among children and young people.

The Irish Heart Foundation is calling for a 20% tax on sugary drinks in the next Budget.

It says this would raise in the region of €60m and reduce the number of obese people by 22,000.

The IHF is also asking for funding to be allocated for subsidies for fruit and vegetables, the establishment of a Children's Health Fund to promote good nutrition through education and skills, and the provision of healthier meals in schools.
