Seal campaigners say a cheap beach toy is leaving animals to suffer slow and painful deaths as they step up calls for a UK-wide ban.

Sue Sayer, founder of the Seal Research Trust and chair of the Seal Alliance, is taking the Save Our Seals from Flying Rings campaign to Westminster, urging MPs to act.

She said the plastic rings, often sold for £1 to £2, were being bought in their thousands and regularly lost on beaches before drifting into the sea.
