The SNP has never had a mandate
It is a commonly touted assertion of the SNP that all elections, Westminster or devolved, will be referendums on independence and if they achieve a majority of some kind then this will give them a mandate for independence. But what does ‘mandate’ actually mean?
A standard definition (via Google) of a mandate is:
The authority to carry out a policy, regarded as given by the electorate to a party or candidate that wins an election.
