The death of Charles Kennedy has robbed Britain of "one of the most gifted politicians of his generation", Nick Clegg has said.
Paying tribute to his predecessor as Liberal Democrat leader, Mr Clegg said: "Charles's untimely death robs Britain of one of the most gifted politicians of his generation.
