ALBA MP Neale Hanvey has spoken to Westminster security after claiming another party had “engaged” an investigator to spy on him.

The Kirkcaldy and Cowdenbeath MP, who left the SNP prior to the Holyrood election to join Alex Salmond’s newly formed Alba, said he is seeking advice but will make “no further comment” about the matter.

Hanvey had tweeted: “If another political party had engaged a private investigator to spy on me, either as a member or opponent MP, is there a way to establish and ­challenge this?

“If MI5 are barred from spying on MPs this feels like serious overreach.”

The MP is one of two Alba representatives at Westminster alongside Kenny MacAskill. Both members defected from the SNP citing concerns over the pace of the independence push from their former party.

Hanvey told the Daily Record: “An allegation has been put to me and I am looking for advice.

“I have reported the matter to the ­Parliamentary security team, who have passed on advice on how to secure my devices.”

The House of Commons would not comment on security issues.

Earlier this week Alba sought extra capacity for their upcoming conference – to be held on the same weekend as the SNP conference – as it sold out in under 48 hours.

Last week the party welcomed its 6000th member to the fold with veteran SNP campaigner Moira Brown.
