THE Tories have failed in their bid to win the SNP's most marginal seat with Nicola Sturgeon's party retaking the constituency with an increased majority.

Jim Fairlie won the ballot this afternoon in Perthshire South and Kinross-shire beating the Tories' candidate Liz Smith, the party's former education spokeswoman in Holyrood.

Fairlie, who was a co-founder of Farmers4Yes ahead of the 2014 independence referendum and founded Scotland’s first farmers market, increased the SNP majority by 526 votes.

SNP leader Nicola Sturgeon congratulated Fairlie.

She wrote on Twitter: "Doesn’t seem like a week since Jim Fairlie, Pete Wishart and I were campaigning in Letham in the torrential rain. Fantastic result in a seat that the Tories talked up and some people doubted we would hold."

SNP MP Peter Grant wrote: "Yaaaaas! Another 'probable Tory gain' stays SNP."

Fairlie will be a new face in Holyrood and replaces long serving Roseanna Cunningham who is standing down.

The Perthshire farmer said he was "over the moon to be representing my own constituency".

He added: "It's the place where I grew up, where I was born and spent my entire life. It's a huge huge honour.

"I will absolutely represent the constituents regardless of how they voted."

Returning officer Barbara Renton announced the result just before 2pm to a socially distant reduced group gathered in Bell's Sports Centre, Perth.

Fairlie netted 20,126 votes, taking 45.7% of the vote share, while Smith got 18,178 votes with 41.2% vote share.

Both the Labour and the LibDem vote share fell by 3% and 2% respectively.

Turnout was 70% - an increase of 9% from 2016.
