Glayva whisky liqueur is calling on consumers to "save Britain's drinks cabinets" in its biggest UK marketing push.

The 'Glayva. The Best Liqueur in the World' campaign offers a free 35cl bottle of Glayva to drinkers who upload photos of themselves pouring old spirits down a sink to the brand website.

The six-week push includes press ads and videos on Facebook. "By using social and traditional media we'll resonate with our existing drinkers as well as new, younger customers," said a spokesman.
