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.
After another extraordinary week, we try to make sense of what Trump has been up to on his European travels. From Chequers to Brussels to Helsinki, what was he doing and why was he doing it? Is he really Putin's puppet? Has he helped or hurt May's chances of survival? Plus we catch up with the other side of the Trump presidency: the remaking of the US Supreme Court. How will the nomination of Brett Kavanaugh impact on some of the most contentious issues in American politics, above all the deep divisive question of abortion? With Helen Thompson and Gary Gerstle, Mellon Professor of American History at Cambridge.
