'Christian', as a self-identifier of religious belief, fell below 40% for the first time in 2018 in the UK, while 'non-religious' oustripped all the others combined at 52%.
Coincidentally, the UK voted to leave the EU by exactly the same percentage of those who voted as those who now state they have no religion. On the basis of that margin, the UK is now going through the most fundamental change in its constitution since the restoration of the monarchy in 1660.
The constitutional change as a result of 52% of people having no religion has been conspicuous by its absence. In Theresa May's words, nothing has changed. In this instance though, that statement is true.
