Simon Jenkins is everywhere.

Open a newspaper, and he’ll be there. Another day, another publication, another column.

He’s so busy churning out views that he can hardly be expected to spell names correctly.

But he needs a lesson in Welsh places. In recent weeks, he’s twice referred to ‘Caernarvon’. There’s no such place. It abandoned that anglicised style for Caernarfon around the time 21 year old Prince Charles was invested as Prince of Wales in the town in 1969.
