Somewhat bizarrely the more modern answer might be 'Margaret Thatcher', who is often held up as the UK's Ronald Reagan - but this isn't strictly true. She said that what we'd now call social conservative issues such as abortion, same-sex marriage etc. are 'matters of conscience' - that is, keep it your yourself and let others do their thing. She essentially tabled all debate on these issues. After this, we now have folks such as Tony Blair hiding his Catholicism while being PM as it would have made him almost unelectable, and Nick Clegg former Lib Dem leader being scolded for being an out Christian.
It's a weird, extremely British kind of madness.
In the UK politicians rarely if ever flout their religions. Until modern times Catholics could not even stand for public office.
There have always been many Jews in politics But most people would only recognise Prime minister Disraeli as having been Jewish, but even he became an Anglican aged 12.
Abortion is largely seen as a Catholic Issue in most of the UK. except for norther Ireland where all parties are against it. But by a quirk of the legislature it has been legal since 2019.
Southern Ireland, a catholic country, made abortion legal in 2018. For the most part British people do not care what religion or none, a politician holds. Unlike the USA neither religion nor abortion are significant issues in Political candidacy. Neither are seen as conservative issues.
At one time the Anglican Church was seen as the conservative party at prayer.
This has not be the case for many years, and if anything the Church and its leadership have moved firmly in to the social justice camp. And are far more likely to support socialist and liberal issues.
I would no longer know where to find groups of Tories in a social context, except where they are politically active.
