The Ukip leader was expected to be central to negotiations in both his role as an MEP and as a prominent Brexit campaigner.
But the official Vote Leave campaign headed by Boris Johnson and Michael Gove was quick to distance itself from Mr Farage.
In a deliberate and unbelievably arrogant snub that will horrify millions of Brexit voters, a senior Vote Leave source said: “Nigel Farage’s involvement has come to an end.”
“I have tried for nearly a year to work with these people and fight on a common agenda and they don’t want to know.”
Ukip MEP Mike Hookem said the party’s 24 representatives in Brussels, including leader Nigel Farage, should be central to the negotiations.
He said: “It would be lunacy for Nigel Farage not to be involved in our renegotiation.
Perhaps not so much ‘lunacy’ as a sign that Boris and Gove are planning a ‘Brexit Lite’ deal that sells British interests out – wouldn’t that just be like a Tory?
