Professor Deirdre Heenan:

Thank you for your question. I agree we are living in a post-Covid, post-Brexit landscape and they have dramatically impacted on policy and the policy agenda. If Tony Blair's mantra was "education, education, education", ours in health should be "evidence, evidence, evidence".

We cannot be grappling around in the dark based on anecdotal evidence. It is the job of the shared island unit to develop and produce that evidence or at least make it easier for us to put evidence together in way that it makes sense and everyone can see the logic of what we are saying.
