ANGUS Robertson has officially launched his campaign to become the SNP MSP for Edinburgh Central.

The seat is currently held by former Scottish Tory leader Ruth Davidson with a majority of just 610 votes.

Robertson, the ex-SNP Westminster leader, faces competition from MP Joanna Cherry to be named the SNP’s candidate ahead of next year’s Holyrood election.

Announcing the start of his official campaign this morning, he said: “Edinburgh Central is a key constituency for the SNP to secure a pro-independence majority in next year’s Scottish Parliament elections.

“At present Ruth Davidson holds a seat for the Tories with a tiny 610 vote majority. And I believe that I can win here with the support of SNP members and voters of all parties who don't want to see the area represented by a pro-Brexit MSP.”

Robertson added: “I grew up in Edinburgh Central, I work here today and this is where I live. And I understand the different issues that matter to people and communities, right across Edinburgh Central.

“So if you want to elect a hard-working local MSP with high-profile national experience, who will support First Minister Nicola Sturgeon and deliver independence, please support my campaign.”

The ex-SNP Westminster leader – who lost his Moray seat in 2017 – has previously questioned the credentials of SNP rival Cherry.

He warned locals that his former Westminster colleague simply can’t be a “full-time candidate”.

Cherry has made clear she will stand down from the House of Commons if elected.

One pro-Robertson SNP insider told The Sun earlier this year that the contest was “a battle for the soul of the movement and party”.

Two Panelbase polls released in the past two months have put the SNP on course for a majority at Holyrood, while also showing 54% support for Scottish independence, when undecided voters are removed.
