A statue is unveiled to mark 200 years since the birth of Karl Marx

It's two-hundred years since the birth of Karl Marx - the German philosopher who came up with the theory of Communism. To mark the event - a statue of him was unveiled in his home town of Trier. The huge bronze cast was a gift from China - whose leader Xi Jinping has described Marx as the greatest thinker of modern times. But as the BBC's Tim Allman reports - many in his hometown don't share that view.
