Union on BBC Two review: a complex look at what it means - or not - to be British

On May 1, 1707, the United Kingdom was born when the Act of Union came into effect: bringing Scotland, Wales and England together. More than three centuries later, the country stands at a crossroads. In Scotland, the debate over independence persists despite a 2014 referendum intended to settle the matter once and for all. The possibility of reunification in Ireland has grown following the turmoil caused by Brexit. And even in Wales, the latest polling shows that one in three people would welcome an independence vote next year. From the Rhondda Valley to the docks of Dundee, there is growing disillusionment with the rule of Westminster.
