'Can I call you sugar? Only if I can call you fatty': Apprentice star accused of bullying plus-size model after posting abusive reply to her cheeky message

Lord Sugar (right) has become embroiled in a Twitter row after replying to a cheeky message from plus-size model, Elena Raouna, 23 (left), from Doncaster, and saying: 'As long as I can call you fatty' (inset). The row sparked when Miss Raouna, who won Miss British Beauty in 2013, sent him a message which said: 'Evening sugar ;-) can I call you that? Lol'. His response has been retweeted by more than 1,400 of his 3.8million followers, but has sparked outrage from many who have branded him a 'cyber bully'. Miss Raouna, a size 16, is now demanding an apology from the Apprentice star and branded his message 'childish, immature and rude'.
