Whether there is still such a thing as “the Catholic vote” in UK elections is a moot point – no parties seem particularly keen to chase it, even if there is. Nevertheless, there are certainly millions of Catholic voters. Overall, self-identified Catholics add up to around 8 or 9 per cent of the population, though this varies from region to region. Significantly, some of the main battleground areas of Election 2019 – the so-called “Labour Leave” strongholds of the North and Midlands – also happen to coincide with several of the Church’s traditional heartlands. How Catholics vote may, therefore, have an important influence over this country’s political future.
