With more than 120 world leaders coming to Glasgow for the UN climate summit, it should have been a once in a generation chance to show off the very best of Britain to the watching world.

Instead, Joe Biden, Emmanuel Macron and others will be greeted by rubbish-strewn streets, gridlocked roads, cancelled trains, glued-down protesters and a plague of rats after a city under SNP leadership became a “midden”.

Refuse workers and train drivers have announced they will go on strike during the entire 13 days of the conference, prompting warnings of “world leaders stepping over bin bags” and a “humiliation on the world stage”.
