THE Downing Street branch of the Scottish independence movement, also known as the Union Unit, has been playing a blinder recently. It advertised for a leader who could make a case which would convince sceptical Scots that they should remain in the Union, but did not consider that knowledge of Scotland might be important. When they did appoint someone, it was actually a Scot, former MP Luke Graham, but he didn’t last long before he fell foul of the internal politics of Downing Street and was sacked. Next up was Dominic Cummings’s chum, Oliver Lewis, known as “Sonic”, who lived up to his name in the speed with which he arrived, and departed, apparently at the behest of power behind the PM, Carrie Symonds, without making any impression whatsoever.
