Divers clear rubbish from the Pembrokeshire coast
A team of divers - known as Neptune's Army of Rubbish Cleaners - are stepping up efforts to keep Britain's coastline clean and litter free.
Everything from shopping trolleys, car batteries, bikes, fishing tackle and even a kitchen sink have been removed from the sea bed and recycled where possible.
