Queen extends her reign to top list of most powerful women in Britain She's been tipped as a future Tory leader - and today Theresa May's rise to prominence is confirmed with the news that she has been voted the most powerful woman in Britain after the Queen. The Home Secretary, whose political star has soared since her popular decision to block the extradition of autistic hacker Gary McKinnon, came out ahead of a host of leading female business figures and judges in the list compiled by BBC Radio 4's Woman's Hour. While the list is - perhaps inevitably - headed by the woman who has spent 60 years on the throne, there is no place in the top 100 for the Duchess of Cambridge. And the ranking also hints at the lack of racial equality among the country's most powerful women with every member of the top 20 being white. Kids Company founder Camila Batmanghelidjh and Iraqi-born architect Zaha Hadid are among the few ethnic-minority women on the list. Among the women who made the top 20 is third-placed Santander chief executive Ana Botin, who ran an internet start-up business before joining the bank. She is joined by media tycoon Rupert Murdoch's daughter Elisabeth, the chairman of television company Shine Limited, who has thus far come through the scandal surrounding other members of her family relatively unscathed and is ranked fifth. The inaugural Woman's Hour Power List was compiled by a panel of judges including author and journalist Eve Pollard, Conservative MP Priti Patel, television presenter and writer Dawn O'Porter, Labour peer Oona King, novelist Val McDermid, and former Woman's Hour editor Jill Burridge. Eve Pollard, the panel's chair, said the judges set out to include women who wield power, rather than simply influence, hence the decision to exclude Kate Middleton. Inevitably not everyone will agree with the 100 we have chosen. There are some omissions. For example, we had long debates about the Duchess of Cambridge. Is she influential? Hugely. Is she powerful? Not yet," she said. What this list does is shine a light on those sectors where too few women are getting to the top, like politics, FTSE companies, the military and journalism. Our legacy, we hope, is that this list might change that.
