evidence: The UK now has guarantees that it won’t have to make more than a 16% net contribution to Horizon Europe, according to UK and EU sources, a reassurance that has allowed today’s deal to go ahead. [...] The TCA itself hasn’t been amended – neither side wanted to open that can of worms – but negotiators have now firmly agreed that the UK’s net contribution will be capped at 16% (apart from small administrative fees on top of this). [...] That meant it was a big net winner from the Framework programmes because UK scientists were so successful. That needs to be viewed in the context that overall the UK was a net contributor to the EU budget, and as a member of the union could not pick and choose which programmes to join.
