That's an interesting question.
Tbh it depends on your idea of obscure and what constitutes a cult I suppose.
I could maybe point out Eric Pickles (tory MP for Brentwood & Ongar and Shadow Secretary of State for Local Government ) who has been getting very
cozy with an obscure US evangelical fundy group the Peniel Pentecostal Church
have set up in his constituency (as well as things like tithes they're one of those all encompassing groups.....it's not only a church but you bank
with their bank, have your mortgage through their mortgage company etc etc).
I'm pretty sure Pickles isn't a member of the group but I know there has been much comment about his need for their votes prompting a long silence
over their buying up large numbers of houses in Essex villages
(it's near where I used to live in England and one man I spoke to about talked about people feeling forced out by the religious zealots).
You'll also maybe find people like the Northern Irish DUP MP's religious views cultish or obscure.
Very fundy evangelical, very very 'literal' in their Biblical tastes.
At it's most extreme they're quite Calvinist....all stuff about 'the Elect' etc and the Roman Catholic Church being satanic.
Perhaps one or two Scots are quite Calvinist too (Calvinism does after all hail from Scotland).
Recently we also had a little frisson of excitement over Ruth Kelly (SoS for Education) because she is a member of Opus Dei.
Mention 'Opus Dei' and lots of people start giggling about self-flagellation and strict Roman Catholicism.
I can't say as I've seen much that could honestly be claimed to be her forcing her views on everybody else tho.
But to tell the truth Britain just isn't that bothered too much about 'public religion'; the days of an huge interest in someone's private
religious beliefs are pretty much over......although if it comes too public or it comes to light that a proposed law is simply a sop to religion then
'we' tend to not like it much and complain and refuse them.
That's not to say a person's private beliefs are not respected (the recent Gov moves to ally Church fears and concerns on the introducing greater
numbers of pupils from outside of a 'faith group's schools illustrate that well enough) but we are absolutely a secular society where our
'established Church' (the Church of England) holds little public attention.
We really don't go in for public religion or public political declarations about religion very much at all, in fact I'd say it's strongly
disliked......we're nothing at all like the US in this regard for instance.
But I don't think spending lots of effort having to go looking for a few examples of a nearly invisible and odd religion in Parliament is really what
is important or the most productive use of our time tho.
Far more immediate in our concerns ought to be, IMO, the fact that as of Oct 2006 -
In parliament there have only ever been 291 women MPs.
It seems to me that 'we' can't even get a just gender balance right.
That ought to be a major concern to us.
If we keep on excluding from the decision making processes the very people those decisions are supposed to apply to it is no wonder we end up with
poor law, often lacking 'popular support' and ill-fitting the purposes it is intended for?
