Yeah, but given they seem to be proposing that the UK change from its current natural position, to what would be permanent BST, it seems daft. (It would help if they'd included the UTC offsets with their diagram)

I'd suggest that ain't going to happen, especially as the UK is no longer a member of the EU, and so this will be ignored.

As I recall part of the issue with the previous time this was proposed was that the UK intended to continuing observing Summer Time in the summer, and hence it would cause issues for Ireland if it had to stop switching.

I guess we can only wait and see...
