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 ask whether the UK constitution is cracking up - and if so, where's the breakpoint going to come? Is Brexit at the heart of the current crisis or does it go deeper than that? What's the role of the Supreme Court? And the Queen? Could the Bank of England play a part? And where does Scotland fit in? We try to piece it all together with Helen Thompson, Chris Bickerton and Kenneth Armstrong.
