Brexit-on-sea: Why do voters on Essex's protected coast want out of Europe?

Residents in the Ukip stronghold of Clacton-on-Sea are rightly proud of their clean beaches, fresh air and wildlife. Would they still vote leave if they knew the things they love about their town are thanks to EU membership?

Audrey James and and Mary Chivers, skirts hitched and shoes off, are paddling with their grandchildren by the pier at Clacton-on-Sea. A huge offshore windfarm spins in the distance and all around them are clean beaches, clear water and protected nature reserves.

But Groyne 41, the name of the beach on the "Essex sunshine coast" where they are picnicking, is the exception, having failed to meet tough new EU water quality tests last year possibly because of the many seagulls living below the pier.
