A good piece by Clare Foges in The Times of London today on how of all the accusations of betrayal that will come post Brexit, immigration not falling will be one.
I'm not sure why people thought immigration would fall. I distinctly recall Farage, during one of the TV debates, saying that EU workers could be replaced by workers from the Commonwealth, with more firmly established ties with the UK.
Besides, pretty much every person who voted for Brexit on NSC has said that it wasn't about immigration so no-one is going to aggrieved or feel 'betrayed' if non-EU immigration goes up
