Not any longer but one might have thought of Britain as a theocracy at some point in the recent past insofar as members of the governing party would have put down Christian in the box marked Religion. On the other hand, in 2025, formal occasions in the UK usually take place in Christian cathedrals and churches. The King (albeit with no executive powers in the Government) is head of the Church of England - the 'Supreme Governor of the Church of England'.

Interesting that 20% of Israelis do not believe in a deity. 18% are Muslim. In Iran, Jews are 0.03% of the population.
