I get about Colwyn Bay, Rhyl, Abergele, Prestatyn, and Llandudno and have a pretty good grasp of the local demographics. So to answer your question, "Yes, and recently." Whilst I will concede that CB has had problems in the past, it has improved over recent years, and providing that trend continues we are on the right path. However, it is up to those in Authority to make positive rather than negative moves to ensure it continues. Criticism of the ongoing situation by Councillors does little to assist integration of incomers and only goes to create doubts or anxiety in the local community.
I have lived in this area, Colwyn Bay and Llandudno, since 1987, after a previous couple of years in the 1970s, so am not new to the area. I have many friends and acquaintances locally and I think my view is fairly representative of theirs.
Bob Squire could, I'm sure, be more positive in his outlook and put across an improving, rather than declining, projection.
