Repetition of history

Sir, - Nicola Sturgeon condemns Theresa May as “unelected” but this implies we have a presidential system, whereas we have a parliamentary system, in which prime ministers hold office through the support of a majority of MPs.

There’s a sense in which history is repeating itself because Douglas Young, wartime leader of the SNP, when encouraging the Scots to refuse conscription, also accused Winston Churchill of being “unelected”. Rev Dr John Cameron. 10 Howard Place, St Andrews.
