John Major was prime minister for longer than the last five we've had in the UK. What were his politics? Were they little more than Thatcherism with some of the hard edges taken off; or did he represent a more significant shift of the political dial.  Thanks to Dr Ben Williams for joining me on this one to unpick these questions (and a few more besides!) Ben co-wrote the  edited book John Major: An Unsuccessful Prime Minister? Reappraising John Major with Dr Kevin Hickson.
