On 11 September, 1997, Wales and Scotland voted for devolurio in referendums.
Both referenda resulted in a devolved future, Scotland having a parliament with reasonable internal authority, Wales a less powerful Assembly.
Since then, Holyrood had gained further powers whilst both the Lab/Lib and SNP administrations have governed her, and further powers are due to come into force in April.
However, Brexit may well mean a 'power grab' by Westminster - and a diminution of Holyrood's powers.
Has devolution been good for the UK?
