Scotland's political leaders and other high-profile figures have come together to pay tribute to Scottish motor neurone disease (MND) campaigner Gordon Aikman after his family announced he had died aged 31.
Aikman, a former Scottish Labour activist, was diagnosed with MND in 2014 while he was working as director of research for the Better Together campaign in the Scottish independence referendum.
His campaign, Gordon's Fightback, has raised over £500,000 for MND research since it was created after his diagnosis. He also persuaded Scotland's first minister to double the number of MND specialists in the country.
Aikman is survived by his husband, journalist Joe Pike, who announced his death on Friday morning.
Nicola Sturgeon paid tribute to the "incredible courage" Aikman showed in the face of his illness.
Scottish Labour leader Kezia Dugdale, a close friend of Aikman's, said she was devastated by the announcement.
Scottish Conservative leader Ruth Davidson called Aikman a "brave and beautiful man".
Former prime minister Gordon Brown called Aikman a "hero" and said his thoughts were with the campaigner's husband and family.
Tony Blair offered his "heartfelt condolences" to Aikman's family and friends.
Scottish Greens co-convener Patrick Harvie said Aikman had "dedicated himself to making a difference".
Scottish Lib Dem leader Willie Rennie described Aikman as a "generous, determined, and gentle man".
Former Better Together director Blair McDougall said he was "filled with sadness".
Journalist Owen Jones, who interviewed Aikman about his campaign in 2014, said he "made the world a better place".
Former Scottish first minister Jack McConnell said Aikman was "a truly special person".
Labour MP Wes Streeting sent his love to Aikman's family and friends.
SNP MP Pete Wishart said the word "inspiration" could have been "invented" for Aikman".
Journalist Chris Deerin said Aikman was a "brave, smart, funny man".
MND Scotland said it was "shocked and saddened" by the announcement.
On New Year's Day, Aikman joked that he "didn't expect to see" 2017.
His final tweet, from Tuesday, thanked Dugdale for raising a further £20,000 for MND Scotland.
