Deputy Prime Minister Nick Clegg has said Prince Charles "is free to express himself" following reports that the royal compared President Putin to Hitler during a private conversation.

Former Polish war refugee Marienne Ferguson said the prince likened some Nazi actions in Europe to those of Russia's Vladimir Putin when they met at a Nova Scotia immigration museum.

Mr Clegg told BBC Breakfast he had never been of the view that, "if you're a member of the royal family you have to enter a Trappist vow of silence".
