Sir Alan with winner Simon Ambrose: The business tycoon branded disgraced Katie Hopkins unemployable after seeing footage of her backstabbing about the other contestants

Sir Alan appeared on the programme with the surprise winner of the £100,000 job to work with the millionaire businessman, 27-year old Cambridge graduate Simon Ambrose.

When asked by host Adrian Chiles to comment on Katie's back-stabbing and bitching about the other contestant's, including her comment about finalist Kristina Grimes's 'orange fake tan', he said: "I don't know what she's thinking.

"Katie's a clever girl, a very, very clever girl. Why she needs to do that type of thing I don't know. She doesn't need to do that at all."

The former contestant was booed by the audience when she walked into the west London studio.

Pantomime villain: The self-dubbed 'alpha female's vitriolic comments have won her no friends during her appearance on show The Apprentice

She squeezed the knee of ex-army lieutenant Paul Callaghan, - the man with whom she had an affair with on the show but whose relationship ended when he caught her with a married man - in support as she made her entrance.

The 32-year-old mother-of-two sensationally took herself out of the competition when challenged by Sir Alan Sugar about her willingness to relocate her two young children from Exeter to Brentwood.

Hopkins, was told she was through to next week's final, only to quit a few moments later.

She has boasted of affairs with three married men, of being "10 out of 10" in bed and was even photographed naked making love in a cornfield with colleague, Mark Cross.

However, the resultant publicity has seen the self-styled 'alpha-female' sacked from her day job as a brand consultant at the Meteorological Office for bringing the organisation into disrepute.

Ms Hopkins confirmed she was planning to take her former employers, the Met Office, to an employment tribunal, over the sacking.

Sir Alan said: "I just don't understand her really, she is a very, very intelligent person and I only hope that one day she will start directing that intelligence of hers in a more productive way.

"I think she will reflect back in a few years time and realise that she may have wasted some time in doing what she is doing now."

Katie's response to Sir Alan's criticisms were: "The pantomime villain lives on."

The controversy surrounding this year's Apprentice continued as 27-year-old Simon Ambrose stole a controversial victory off hot favourite Kristina Grimes to bag the £100,000 job working for Sir Alan Sugar.

The decision shocked many viewers, and some of the other Apprentice candidates were said to be angry with the outcome and considered walking off the Adrian Chiles spin-off show in protest.

Mr Ambrose, whose father and grandfather are both self-made millionaires, will now train as a chartered surveyor while working on a £70 million hotel and golf course development.

The ex-public schoolboy revealed he planned to celebrate by splashing out on a luxury Aston Martin sports car.
