We talk to lawyer and constitutional expert Alison Young about the current pressures on the UK constitution, from Brexit to devolution to political polarisation. Is parliamentary sovereignty still the linchpin of the system? What changed with the arrival of the Supreme Court? Can the constitution survive in its current form?
We try to work out what the current favourite to be next Tory leader actually stands for. Can his time as Mayor of London tell us what kind of PM he might be? Will his journalistic past come back to haunt him? Does he have a political philosophy beyond 'doing Brexit'? Plus we discuss whether the Johnson-Trump comparisons really stand up. With Helen Thompson and Chris Brooke.
