The restrictions on advertising high-fat, salt and sugar products to children will not be extended, ­despite intense pressure from health campaigners.

As part of its final review, published this week, Ofcom recommended no change to the current policy, despite lobbyists calling for a ban on HFSS ­advertising before 9pm.

Since April 2007, HFSS ads have been banned during programmes made for children aged four to 15. "We are satisfied the restrictions have significantly reduced the amount of HFSS advertising seen by children," the review said.
