Britain's newly-appointed Prime Minister Gordon Brown, right, and his wife Sarah wave as they pose outside 10, Downing Street in London. Brown, a self-proclaimed admirer of India, today took over as Prime Minister amid expectations that relations between New Delhi and London would develop further. The 56-year-old Labour party leader was sworn in by Queen Elizabeth at the Buckingham Palace shortly after Tony Blair stepped down after holding the top post for 10 years. Brown, Chancellor of Exchequer, took over as leader of the Labour party on Sunday from Blair who stepped down in the backdrop of decline in his popularity for joining the US-led campaign in Iraq. This is the first time that a changeover has occurred without a general election.
