"A tory high-flyer has been forced to quit after writing a vile, expletivefilled rant about Labour MP Diane Abbott on his Facebook page.
Conservative Future national campaigns co-ordinator Edward Hallam called the respected MP a "foul, ignorant, conceited c***".
He followed his tirade against the Labour leadership contender with: "She'll make a great Labour leader."
Hallam, 25, added: "She's a poisoned well, her policies are hate and bile, and she's intellectually illiterate with a chip on her shoulder."
Derby-born Hallam - a court shorthand writer - featured on the front page of the website of Conservative Future - the Tories' youth movement. After the Sunday Mirror contacted the Party, Hallam's details were removed and he quit his post. Last night he apologised, saying: "It was inappropriate."
A spokeswoman for Ms Abbott said the Hackney North MP did not want to comment on the insults."
