Greenpeace Unearthed found 36 supposed grassroots campaign groups that were actually administered by Conservative staff and activists and which were forums for vile racism, antisemitism and Islamophobic attacks on Sadiq Khan. While the Prime Minister is above such co-ordinated efforts against 20 mph zones in Wales, will he shed some light on these shady groups spreading abuse, including on their funding and their links to his party, and whether he is aware of similar operations existing elsewhere in the UK? If he will not, will he at least commit today to investigating and taking action to tackle the sources of this grubby gutter politics?
