What has changed in India one year on from Delhi rape? The most significant impact, they said, is that their daughter's determination to survive the attack and bring her attackers to justice has inspired more victims to come forward and more women to protest. In a television interview on Monday, the victim's father, Badrinath Singh, said the anniversary of the attack which killed his daughter 13 days later should be "celebrated" as a day to inspire other young women to fight for their safety and rights. "This date should be celebrated so that people keep getting inspired and keep joining this movement, coming together to ensure the safety of women," he told the television channel NDTV. But he added: "It is true what happened to my daughter has caused massive changes in the system, but we still feel that it hasn't yet shown its complete impact. I really pray to God that something like this never happens again and no one has to go through something like this. On Sunday, he said the increased number of rapes, in particular in Delhi, pained his family and left them feeling women would never be safe in India until there was a significant change in social attitudes towards sexual violence. He was referring to figures released in October by the National Criminal Records Bureau which showed the number of rapes in the first ten months of this year was almost double those in the whole of 2012. There had been 1,330 rapes in Delhi from January to the end of October compared with 706 for the whole of 2012. The figures revealed that the number of reported sexual assaults increased from 727 in 2012 to 2,844 in the first ten months of 2013. They also showed increases in sexual harassment - known indulgently as 'Eve-teasing' in India - kidnap of women and physical assaults on brides by their husbands and in-laws. Campaigners for women's safety agree that the increased number of cases reflect an increased willingness of women to report sexual assaults and rapes to police officers they had previously been afraid of. Ranjana Kumari of the Centre for Social Research, which runs rape crisis centres and trains police to be more sensitive to victims, said the figures reflect both an increase in rapes and an increased determination among victims to face the stigma and demand justice. In one rape crisis centre in South West Delhi, 22 women reported they had been raped in January alone, she said. What was different was that in previous years, many of them would not have had the courage or support from their families to come forward. The number of rapes in Delhi has doubled. There should be fewer cases to report, but women are no longer in fear of the social stigma of [reporting] rape," she said. She cites three cases where young women and teenagers from varied backgrounds have reported alleged rapes and sexual assaults by some of India's most powerful people. A former Supreme Court judge, Justice Ganguly, currently chairman of the West Bengal Human Rights Commission, is facing a complaint from his intern that he sexually harassed her. One of India's most prominent, and until recently revered Hindu gurus, Asaram Bapu, is currently in police custody on rape charges. And Tarun Tejpal, until last month one of India's most respected authors and editors, was forced to resign as editor of his own magazine, Tehelka, after one of his staff complained that he sexually assaulted her in the lift at a media festival. He too is now in custody in Goa where he is facing rape charges. Tarun Tejpal, editor in chief of Tehelka.com (AP) All three men deny the charges, but campaigners say it's likely the victims would never have had the courage to complain to the police before the outcry over the Delhi gang-rape and murder. The case of Tarun Tejpal, who has admitted trying to force a young employee and daughter of his friend into a sexual encounter in a hotel lift, has caused the loudest reverberations. Mr Tejpal's Tehelka magazine had been one of the Indian media's strongest champions of women's rights and had regularly reported the abuse of women rape victims by senior police officers. In one issue last year, his reporters recorded several senior officers explaining that many rape complainants were in fact prostitutes who had not been paid. In a letter to his victim he conceded how far he had fallen from his magazine's high values. I have often spoken for the absolute rights and freedoms of women, and it shames me beyond words, to find myself located in this awful context. I would say it was a moment of insanity, except that would mean evading responsibility for it," he wrote. "Even the best of men in power exploit the women under them," said Ranjana Kumari. The fact that men as influential as Mr Tejpal could be brought to account is progress she said, but there is great disappointment too, she said. The fast-track courts established to speed justice for rape victims have in fact been slower than the regular courts despite official recognition that delays, often for many years, in cases being heard had created a culture of impunity. The fast track courts in Delhi dealt with 380 rape cases this year compared to 547 rapes tried in ordinary cases the year before. A £195 million 'Nirbhaya Fund' established in honour of the Delhi gang-rape victim to help other victims to report cases and rebuild their lives has yet to spend a single rupee of the funds. One of the greatest disappointments however was the government's failure to make rape within marriage a crime. Most marriages in India are arranged between families and the idea of consent within such unions might still be required was widely opposed. The parliament was not prepared to discuss it. A drunken man can come home and abuse his wife with impunity," said Ms Kumari. One year after the Delhi bus rape: what's changed Fast-track courts to hear rape cases - New laws for minimum 20-year sentences for rape - Death penalty for rapes where the victim dies or is left in a vegetative state - Campaigners say women more willing to come forward and report crimes - Number of rapes more than doubles year-on-year - Government refuses to make rape within marriage a crime - £195 million memorial fund to help other victims has not spent a single penny
