What changes if Zack Polanski is an MP?

Could Zack Polanski win in the St Pancras and Holborn by-election – and how crushing would a loss be to the Green Party’s momentum?

Harriet Harman, Ruth Davidson and Beth Rigby discuss – and mull over whether the whole thing will be an early headache for Andy Burnham, or a chance to prove he can regain the confidence of young left-wing voters.

Plus – Harriet responds to criticism from Kemi Badenoch after she talked on our episode earlier this week about Claire Coutinho's shadow cabinet promotion while on maternity leave. She'd joked that the leader deserves a 'woke badge'.
