Boris Johnson has quickly found out it's tough at the top. This week, the Prime Minister has lost more votes in the House of Commons, lost a legal challenge in the Scottish courts and been accused of misleading the Queen over the prorogation of Parliament. It's tough at the top of Labour too as Jeremy Corbyn and his deputy Tom Watson argue over their positions on whether a general election should come before or after a potential second referendum on Brexit. Adam Boulton and guests assess the problems and the divisions for both leaders and, as party conference season approaches, they look ahead to the Liberal Democrats gathering in Bournemouth. Joining Adam this week are the Brexit Party's Claire Fox and the co-founder of Novarra Media Aaron Bastani.
