Police are probing an attack on an MSP’s constituency office after vandals daubed anti-SNP graffiti on the walls and smashed a window in an overnight raid.

Clydesdale MSP Aileen Campbell said she was “saddened” to find the phrase “SNP out” scrawled on the outside of her Carluke base in bright red paint on Wednesday morning.

Thugs also shattered a window at the building in Kirkton Chambers, currently being used as a base for campaigners canvassing in the Lanark and Hamilton East constituency ahead of December’s general election.

Officers are now investigating the incident.

Representatives from across the political spectrum have since sent messages of support to Campbell, who wrote there was “no excuse” for the attack in a social media post.

In a statement on Facebook, she said: “An attack on my office last night, which has been reported to the police, has saddened me deeply. I have a duty of care for the people who work in my office and this is clearly upsetting for them, as well as for the other tenants in the building and our neighbours.”

“People can disagree about politics, but there is no excuse for mindless aggression, vandalism or violence which causes stress and anxiety in our local communities.

“We should strive for a better politics that respects and seeks to understand other points of view and, thankfully, that is how most people conduct themselves.”

She added: “We won’t be dragged down by the mindless act of a minority. We’ll clean this up and my service to my constituents will not be affected and the office remains open.”

“I won’t be swayed from the priority of working hard for Clydesdale and achieving a better, fairer Scotland.”
