Charles Kennedy, the former leader of the Liberal Democrats, has died aged 55.
The Scottish politician died at his home in Fort William on Monday, according to his family. Police said the death is not believed to be suspicious.
"It is with great sadness, and an enormous sense of shock, that we announce the death of Charles Kennedy," Kennedy's family said in a statement issued to the BBC.
"Charles died at home in Fort William yesterday. He was 55. We are obviously devastated at the loss. Charles was a fine man, a talented politician and a loving father to his young son.
"We ask therefore that the privacy of his family is respected in the coming days. There will be a postmortem and we will issue a further statement when funeral arrangements are made."
Kennedy served as an MP for Ross, Cromarty and Skye until May's general election, when he lost the seat to the SNP's Ian Blackford.
He was first elected in 1983 and went on to lead the Liberal Democrats between 1999 and 2006. During this period he led the party to its best ever electoral performance at the 2005 general election and made his name by opposing the Iraq war and university tuition fees.
But Kennedy struggled with alcohol and was forced out as leader when it was clear he had lost the support of his colleagues.
His death leaves behind one son, Donald, with his ex-wife, Sarah Gurling.
Kennedy was just 23 years old when he was first elected to parliament.
