Back in May 1994, the then chancellor made the trip to Glenfarclas distillery to fill and lay a cask in the production site's warehouse vowing to only return to open it when the local constituency voted in a Conservative MP.
In the period since the area had remained an SNP stronghold, that was until 2017 when Douglas Ross won back the seat for the Tories.
This year, Mr Clarke was invited back by Mr Ross to finally open the cask.
Reportedly set to be dubbed the "Chancellor's Cask", it will be bottled with all proceeds going to a charity of Mr Clarke's choice.
