Tui’s services to destinations including the Spanish hotspots of Majorca, Tenerife and Ibiza have all been cancelled, with flights due to resume again in October.

Dooey said Spain’s omission from the Scottish government’s quarantine exemption list, published on 8 July, had led to “insecurity for both holidaymakers and the travel trade”.
