Charles Kennedy, the former leader of the Liberal Democrats, has died at the age of 55.

Mr Kennedy died at his home in Fort William. Police are yet to give a cause of death but say it is not being treated as suspicious.

Prime Minister David Cameron, Mr Kennedy's successor Nick Clegg and Scotland's First Minister Nicola Sturgeon have led the tributes.

Mr Kennedy led the Liberal Democrats from 1999 to 2006, but lost his seat at last month's general election. In 2005, he led the Lib Dems to its best ever election result after fierce criticism of the war in Iraq.

Despite the 2005 result, he stepped down as leader of the party after revealing he had been receiving treatment for alcohol addiction.

Nick Clegg said his predecessor had "more political talent in his little finger than the rest of us put together".

"Charles devoted his life to public service, yet he had an unusual gift for speaking about politics with humour and humility which touched people well beyond the world of politics," he said.

"He was one of the most gentle and unflappable politicians I have ever known, yet he was immensely courageous too not least when he spoke for the country against the invasion of Iraq."

Mr Kennedy's family said in a statement: "It is with great sadness, and an enormous sense of shock, that we announce the death of Charles Kennedy.

"We are obviously devastated at the loss. Charles was a fine man, a talented politician, and a loving father to his young son."

A Police Scotland spokesman said: "Police officers attended an address at Fort William on Monday, June 1 to reports of the sudden death of a 55-year-old man. Police were notified by ambulance service personnel. There are no suspicious circumstances."
