Where Power Stops: politicians and the limits of power

We're entering week six of President Donald Trump's impeachment inquiry and its yet to be seen whether he'll be removed from office - or whether he'll even come close. So if they do exist, how do you stop abuses of power in the highest of offices and what are the limits on leaders' power? In "Where Power Stops" Professor of Politics at Cambridge University, David Runciman looks at the extent to which character has defined and limited the power of recent leaders in the UK and America. David Runciman is the author of six previous books, including How Democracy Ends and hosts the widely acclaimed weekly podcast Talking Politics.
