Former MSP Tom McCabe Dies
Former Labour MSP Tom McCabe has died at the age of 60, the party has said.
He went on to serve as finance minister and held a number of other senior positions in parliament, but lost his seat as the SNP swept to power in 2011.
Tributes have been paid to the politician who died at home after a short illness.
Scottish Labour leader Jim Murphy said: ''The thoughts and prayers of everybody in the Scottish Labour movement are with Tom McCabe's family today. That he has died at such a relatively young age and with so much still to give makes it harder to understand and accept.
''Tom McCabe was a good man. He was a dedicated servant of the Labour movement, and was a radical Finance Minister in the last Scottish Labour Government.
''I always enjoyed Tom's company - except on the golf course, where I could never beat him.
''The dignity he showed in his final few months should act as an inspiration to us all. He will be hugely missed.''
First Minister Nicola Sturgeon wrote on Twitter: ''Very sad to hear of the death of former Labour MSP, Tom McCabe. He was a genuinely good guy. My thoughts are with his wife and family.''
Labour's Margaret Curran also took to Twitter to offer her condolences.
She wrote: ''Very sad news about Tom McCabe he was very good to me over the years and will be missed greatly. My thoughts and prayers are with his family.''
The Scottish Parliament's Presiding Officer Tricia Marwick said: ''I am so sad to hear the news of Tom's passing.
''He was devoted to his family, in particular to his wee daughter Ava. His joy when she was born and his delight in watching her grow was apparent to all around him.
''We worked closely together on the Parliamentary bureau in the early days of the Parliament and then again when we were both elected to the Corporate Body.
''Tom made an immense contribution to the Parliament and his expertise has been sorely missed since 2011.
''My thoughts and prayers are with his family.''
Ms Sturgeon added: ''Tom had an impressive record of public service as an MSP and as a minister in the first post-devolution administration.
''He was someone who was widely liked across the political divide, and will be remembered as such across Scottish politics. My thoughts are with his wife and family.''
Deputy First Minister John Swinney said: ''Tom McCabe was a distinguished predecessor of mine as finance secretary, and despite the fact that we came from different political traditions, he gave me wise advice on how to take forward my work in this role and I am profoundly grateful to him for the generous way in which he offered it to me.
''Tom had much more to give to life in Scotland and it is tragic that he will not be able to do so. I extend my sympathy to his family at this desperately sad time.''
It's predicted the Tories could win a number of seats in Scotland.
Police Scotland say the "targeted attack'' happened at the man's home in Uddingston.
