In some manufactured goods sectors where more complex products have the potential to pose a higher risk to consumers, patients or environmental safety, a greater level of regulatory control is applied. The European Medicines Agency (EMA), the European Chemicals Agency (ECHA) and the European Aviation Safety Agency (EASA) facilitate part of these regulatory frameworks. In line with the UK’s objective of ensuring that products only go through one approval mechanism to
access both markets, the UK is seeking participation in these EU agencies, as an active participant, albeit without voting rights, which would involve making an appropriate financial contribution. The UK would want to secure access to relevant IT systems, ensuring the timely transfer of data between UK and EU authorities
So to be part of these systems (that we currently are) since this is deemed to be a good idea, the country will have to pay, but will have no influence or voting rights. Yeh! – go us…..
