The title is written specifically for UK readers, the actual subject is about the point of alignment leaving GB.

(Also for anyone who was confused by this, it's not about the poles, it's about the point where the bearings for all three norths are equivalent. So a "compass" would point in the same direction regardless of what kind of north it reported. Took me a moment to understand!)

For most of Great Britain, the grid north differs from true north because the grid cells are fixed size, so they "fan out" compared to longitude lines. The exception is the 2°W meridian where the grid lines up.

The magnetic north wanders around, and it now happens to match along the 2° meridian.

But really the article is a year early, as the alignment point should make a brief landfall in Scotland late next year (which the article acknowledges later on). Or perhaps they expect Scotland to secede before that.

Love that, sounds like something Douglas Adams or Terry Pratchett would write :)

How can "north" be a place? I feel like they forgot to add the content.
