A member of the Seanad wants to clamp down on ice-cream vans.

Fine Gael Senator Catherine Noone says the chimes of ice-cream vans are an aggressive form of marketing to children.

She says the 'pester power' of ice-cream vans could be contributing to the problem of child obesity.

She says parents are struggling to control what their children are eating because of how popular ice-cream vans are.

But the Senator says she is not trying to be a killjoy.

Catherine joined John Keogh on Newstalk Lunchtime to discuss the issue.
