Eleven MPs have now left their political parties to join the Independent Group. The Guardian’s political editor, Heather Stewart, asks whether Brexit is pushing British party politics to breaking point. And: Nosheen Iqbal on Sajid Javid revoking Shamima Begum’s citizenship

On Monday, seven Labour MPs left their party and and set up the Independent Group. On Tuesday they were joined by another Labour MP. On Wednesday three Conservatives also defected: Heidi Allen, Anna Soubry and Sarah Wollaston. Is this the start of a new centrist party?

The Guardian’s political editor, Heather Stewart, covering for Today in Focus host Anushka Asthana, speaks to Jessica Elgot, the Guardian’s Westminster correspondent, about what the Independent Group stands for. She also speaks to Alison McGovern, the Labour MP and vocal remainer who has disagreed with Jeremy Corbyn on many issues but does not believe breaking up the party is the solution, and Robert Halfon, the Conservative MP who does not intend to leave his party but wants to radically change it from within.

Finally, Nosheen Iqbal examines Sajid Javid’s decision to revoke the citizenship of Shamima Begum, the Bethnal Green teenager who left the UK in 2015 to join Isis.
