The Church of England still seemed an essential part of Englishness, and even of the British state, when Mrs Thatcher was elected in 1979. The decades which followed saw a seismic shift in the foundations of the C of E, leading to the loss of more than half its members and much of its influence. In England today 'religion' has become a toxic brand, and Anglicanism something done by other people. How did this happen? Is there any way back?
