HEARTFELT tributes have been paid to a Renfrewshire SNP activist who has suddenly died at the age of 34.

John Clark, who was head of office for Renfrewshire North and West MSP Derek Mackay, lost his life while holidaying in Denver, Colorado, on Sunday.

Mr Mackay said he was 'devastated' by John's death and described him as 'irreplacable'.

The Finance Secretary said: "This tragic loss of my friend and colleague is devastating to his family, friends and the cause he served with such commitment.

“John, a gentle giant of a man, is irreplaceable as he was the most trustworthy, loyal and hardworking person I have ever had the privilege to call my friend. 

“John was a rock to many, not least myself. He was one of life’s good guys and will be sadly missed but never forgotten.” 

John, who grew up in Renfrew but more recently lived in Paisley, narrowly missed out on becoming a councillor in Renfrewshire two years ago after running to repesent the Paisley Northeast and Ralston ward.

The area's SNP group said he had a 'bright future' in politics and was highly regarded within the party.

John was also a committed fundraiser, having coined in almost £2,000 for the British Heart Foundation back in July after walking 42 miles of the 62-mile trek from Glasgow to Edinburgh.
