# List of current members of the British Privy Council

This is a list of the members of the Privy Council of the United Kingdom, along with the roles they fulfil and the date when they were sworn of the council. As of March 2025, there are 744 members on the council. The prefix The Rt Hon. is omitted here, because every counsellor bears it, as is the postnominal PC, as every counsellor who is also a peer uses it.
The council is composed mostly of politicians (both members of the UK government and parliament, and members of the devolved governments and legislatures) and civil servants, both serving and retired (since membership is for life). Among those politicians generally sworn of the council are ministers of the Crown, the few most senior figures of the Loyal Opposition, the UK parliamentary leader of the third-largest party, the first ministers of the devolved governments (including, in the case of Northern Ireland, the deputy first minister), and the speakers or presiding officers of the UK parliament and the devolved legislatures. Besides these, the council includes a few members of the Royal family (usually the consort and heir apparent only), more than two hundred senior UK judges (the Supreme Court justices, the senior judges of England and Wales, as well as the senators of the College of Justice of the Inner House in Scotland) and a few clergy (the three most senior Church of England bishops, namely the Archbishop of Canterbury, the Archbishop of York and the Bishop of London).
