Mark Drakeford: 'Ample evidence' ads influence children
Television adverts promoting food which is high in fat, salt and sugar should be banned until after the 21:00 watershed, Wales' health minister said.
Mark Drakeford wants the UK government to take action in a bid to improve diets of children and young people.
He said soft drinks are the main contributor, with chocolate, cereals, biscuits, buns, cakes and pastries all making significant contributions.
UK Public Health Minister Jane Ellison said a strategy was being developed.
