Britain’s membership of Horizon, which funds research projects tackling crucial issues from the climate crisis to terminal diseases and improving food and energy security, was agreed as part of the post-Brexit trade deal in 2020. But it was never ratified in a tit-for-tat row between the EU and the UK over Northern Ireland Brexit arrangements.
I actually think the opposite. Moves like this are part of a slow transition towards one of the awkward “basically a non-voting member but the population takes pride in not being a member” situations like we see with Norway or Switzerland
We hated having a significant veto power to laws/projects we didn’t like. Now we’ll just adopt them for convenience with no seat at the table. :)
