- Ten-Second Biography
Vadera was made a junior minister at the Department for Business, Enterprise and Regulatory Reform in January after a brief stint at the Department for International Development. Before that, she was one of Gordon Brown's most trusted advisers when he was chancellor.
- What is her Background?
Born in Uganda but grew up in India before going to study at Oxford. Went on to gain 14 years' experience as an investment banker.
- Where does she sit politically?
Vadera is regarded as so in tune with the PM's thinking that some in Whitehall refer to her as 'Brown's representative on Earth'. Not massively liked by the left, partly because she previously negotiated the sticky areas of public-private partnerships and private finance initiatives at the Treasury.
- Why is she one to watch?
Brown appears to have closed the big tent to outsiders and is once again relying on a trusted inner circle in his battle for survival. The person leading recent negotiations with energy companies to help families with fuel bills was not the Chancellor Alistair Darling, but Vadera.
- Something you might not know
Vadera is said to have shouted at Tony Blair on more than one occasion. In November 2007, The Daily Telegraph quoted an official as saying: 'She would even tear a strip off Tony for failing to get development policy right.'
