You seem to trust his judgement on Starmer following his manifesto. Yet Starmer has said nothing about cutting immigration numbers, like UKIP would. The manifesto Farage is talking about says he would enact a five year school ban on migrants. Starmer is not for this.
We can disagree on Starmer’s immigration policy, and I am not overly keen on it, without saying it’s like UKIPs. That’s a line by Farage to try and undermine the government and escalate Labour infighting.
