JK Rowling has hit out at Jeremy Corbyn on Twitter – implying that the hapless leader of the Labour party gives her sleepless nights.
When asked by a fan on Twitter “what you do when you can’t sleep?” – she snapped back: “Try to stop thinking about Jeremy Corbyn”:

The blow will be particularly stinging for Corbyn, who has racked up several trendy celebrity supporters including Harry Potter star Daniel Radcliffe, SJW pop star Charlotte Church and noted Hobbit Martin Freeman.
The Corbynistas of Twitter, however, didn’t take it lightly – some suggesting their leader is being abused:
This is an absurd vendetta. The amount of people who will take any opportunity to hurl abuse at him is bizarre https://t.co/XOyIraIoHr

Rowling was once a staunch supporter of the Labour party, and gave them a £1 million donation when they were in government under Gordon Brown.
She has since made two much smaller donations, of £4,000 each, to the local party and the office of deputy Labour leader Tom Watson, who has repeatedly clashed with Corbyn.
Corbyn. Is. Not. Dumbledore.https://t.co/yjyK5ZmAXe https://t.co/bYI0wbTpuJ

It seems the civil war pulling the party apart for the past year has sapped some of her enthusiasm away.
The blow must have been especially painful for Corbynistas, who share the belief with diehard Potter fans that bearded old men can defy the laws of reality.
