Deletion of SNP Trade Union Group

Comment: The article in the ''The Scotsman'' is an opinion piece, it's not clear to me that the 5-person ''Source News'' is a reliable source, and I only see passing mentions in the books ''The Scottish National Party: Transition to Power'' and ''States Falling Apart?: Secessionist and Autonomy Movements in Europe''; I wouldn't count those towards /. The article from ''The Herald (Glasgow)|The Herald'' is significant coverage and a reliable source that should count towards GNG/ORGCRIT. Are there others though? I could only find passing mentions elsewhere
