UNITE general secretary Len McCluskey praised Jeremy Corbyn yesterday for being the first Labour leader to put forward a “serious” alternative to Trident.

Unite is holding its first-ever Scottish policy conference in Clydebank — just 20 miles from the nuclear submarine base at Faslane.

Mr MrCluskey, who represents workers that build and service Trident submarines, warned that simply scrapping the weapons system could “devastate” communities which depend on the jobs.
