The Establishment care about UKIP.
"Labour's loss has been UKIP's gain"
...
"Where Labour speaks at people, UKIP, with Farage to the fore, speaks to them. And in doing so, it shows how far removed the party-political establishment, and Labour in particular, is from, as Mann puts it, ‘the real world’.
In this, this slow-mo conquest of Labour’s one-time social constituency, this ability to speak to people and promise to take back what Westminster has taken, UKIP’s rise has an unexpected echo: the Scottish National Party. Yes, the SNP is pro-EU, and doesn’t like cigarettes or booze – both of which would have Farage turning in his political grave. But the parallels are there. Both parties, rhetorically at least, resist the ceaseless cosmopolitanism of a distant elite, and both play upon a sense of cultural imperilment. The Tories may have won the election, but the political shift is not Conservative – it’s something rather more populist than that."

'then UKIP shouldn't give it to them'
Farage doesn't want to, but here will be plots from withn UKIP and the Establishment will rub its hands and the media will encourage it to continue.
It's an existential battle. The politically correct crowd feel they have Farage on the ropes. The Establishment are holding their breath and hoping this may be the end of Farage and the insurgency.
They hoped Farage was gone, but he fooled them, now they hope a politically correct rebellion may topple or weaken him. But I think the millionaire backers and UKIP voters prefer Farage.
"However, the Conservative joy at having “cut off the serpent’s head” was somewhat tempered by suspicions that the Ukip beast may still prove to be a hydra."
