London, May 31 :    London, May 31:  The only Indian woman to be included in a group of six men and six women, held incommunicado in a sealed house and watched 24 hours a day on a reality television programme called Big Brother, has quit the show last night after less than a week. Sunita Sharma, 25, a trainee barrister who was picked from a pool of 1,50,000 people who applied to get on the programme, the third in the Big Brother series, said that nothing had prepared her for the uncomfortable experience of having her privacy invaded and being watched all the time by cameras. The first two series achieved high audience ratings by showing couples engaging in acts of physical intimacy. Every week the public votes to evict one resident until finally a winner remains. Although Big Brother verges on the crude and the house mates are drawn from the rougher, more uneducated end of society, the programme has a huge following and reflects the new Britain. Sunita's departure was considered a big enough event to be shown live last night on Channel 4 Television, which broadcasts the show. Yvonne Taylor, the head of press at Channel 4, said the programme routinely drew audiences of between 3.5 million and 6.8 million a night. But last night, when Sunita left, nine million switched on. 'She will be replaced over the weekend,' she added. Taylor said that Big Brother had originated in Holland and had proved a 'phenomenon' in many European countries, including Germany, Russia and Spain, but had been a flop in the US. 'Big Brother is popular with a young audience, aged 16-35,' she said. A commentator remarked: 'Sunita Sharma was born in Royal New Cross Hospital, Wolverhampton, she has nine GCSEs, three A Levels, one S level; she is a trained barrister; she has been in the house 141 hours, 26 minutes, 15 seconds.' On emerging into the outside world through the back door of the house specially constructed for television, Sunita had to face several photographers and reporters. She explained her decision to leave: 'It was hard and I did have some issues. I lost a lot of enthusiasm going into the house and I didn't feel I was coming out, being myself. Once you are in the house, you don't realise what's going on the outside. There are cameras there. I am quite a private person.' There has been only one other Indian on Big Brother, on the second series last year - a extrovert and engaging Punjabi woman, Narindar Kaur. Sunita said she had not anticipated what it would be like. 'I did not think what it was going to be like when I went into the house, about the after consequences. It's madness.' She had applied unsuccessfully to get on to the second series of Big Brother before striking it lucky the next time. In her audition papers, she had claimed she was 'uninhibited, very sexy, and have the x factor. You might love me, you might hate me but you will love watching me'. But last night she admitted: 'I had issues from the start going into the house. Every single night I was in the house I was thinking in my head, 'Do I really want to do this? Careerwise, was it the right thing to do?' ' She went on: 'I was very aware of the cameras the whole time. It can get a bit claustrophobic.... I didn't want to be something I wasn't.'
