It’s still interesting to discuss since they’re going to be leader for years

Only one year, unless he’s re-elected. The GPEW hold leadership elections every 2 years, but it was postponed last year so as to not coincide with the general election.

Those 2 constituent countries fly under the Union Jack.

It’s still inaccurate to call them ‘the UK’s Green Party’ as both Scotland and Northern Ireland have their own Green parties which are separate from the GPEW.
