The Guardian's political editor Pippa Crerar assesses the latest developments at Westminster.

Following a turbulent week for the government, with talk of plots to replace the Prime Minister and speculation over the budget, Pippa speaks to two Labour MPs, Chris Curtis and Rachael Maskell, about the mood on the Labour backbenches.

To discuss the challenges for BBC following the resignation of its director general, Pippa speaks to Conservative peer Tina Stowell, a former Head of Corporate Affairs at the BBC and Anna Sabine, the Liberal Democrat spokesperson for Culture, Media and Sport.

To discuss the state of the prison system, Pippa is joined by former Conservative Justice Secretary David Gauke who, earlier this year, carried out a review into sentencing for the government.

And, to give their take on a difficult week for the Prime Minister, Pippa is joined by the political editor of the News Statesman magazine Ailbhe Rea and Luke Tryl the Managing Director of the polling company More in Common.
