"Brown welcomes Thatcher to No 10
Former prime minister Baroness Thatcher has left 10 Downing Street after a meeting with Gordon Brown. Lady Thatcher, 81, spent more than two hours at her former home, where she was greeted with a warm handshake from the current prime minister.

Mr Brown recently surprised many by praising Labour's long-time political foe as a 'conviction politician'. The Tories said they were 'relaxed' about the meeting, pointing out that she had previously met Tony Blair. The visit followed an exchange of letters between Mr Brown and Lady Thatcher, who led the country from 1979 to 1990, shortly after he became prime minister in June."

I guess she is so impressed at how Blair and now Brown have continued her policies with New Labour, she wanted to thank him in person.
