Polanski was elected leader in September and the party's membership has doubled in a short time to 140,000 and counting. Under Polanski they are moving in an economically populist, socially woke direction while also having a visible contingent of more socially conservative Muslims, including deputy leader Mothin Ali. They only have 4 seats out of the 650 in the House of Commons, but will likely be one beneficiary of Labour's collapse in popularity at coming elections, especially where tactical voting is utilised.
The new membership likely contains many of the same people who joined Labour under Jeremy Corbyn, minus the ones who are more critical of NATO and the EU and the ones who don't want men in women's sports. Polanski was previously a Liberal Democrat and was actually critical of Corbyn over the EU and antisemitism.
In recent years the party has had to pay out for
discriminating against gender-critical members and has kicked people out of the party for trying to draw attention to
horrific safeguarding issues.
