Boris Johnson is turning into one regular headache for Prime Minister Rishi Sunak. So this week Christopher Hope is looking at three spheres where the former PM is intent on sticking his oar in.

First, the Brexit impasse in Northern Ireland. The DUP's Sammy Wilson joins Chopper to discuss whether Boris' interventions on a trade deal are helpful, whether a change in Westminster leadership could make a difference, and casts doubts on whether Rishi Sunak even understands the concept of the Union (ouch).

Also on the podcast, the Chair of the Conservative Democratic Organisation, David Campbell Bannerman discusses why the Tory grassroots are revolting, and whether they're punishing the MPs that overthrew Johnson. Plus Chair of the Defence Select Committee, Tobias Ellwood, on whether the former PM is right to push for fighter jets for Ukraine and why he thinks the conflict will last for years.
