It’s her first overseas trip in 24 years.  Aung San Suu Kyi will address lawmakers from both houses of the British Parliament today, one of the few non-heads of state to be given the honour.

The opposition leader for Myanmar, also known as Burma, follows dignitaries including South African President Nelson Mandela, Pope Benedict XVI, and U.S. President Barack Obama in giving a speech in Parliament’s medieval Westminster Hall.

She also is due to meet Prince Charles and his wife, Camilla, and to hold talks with Prime Minister David Cameron at 10 Downing Street.

Suu Kyi spent many years under house arrest in Myanmar. She has visited Switzerland, Norway and Ireland and is spending a week in Britain, where she studied and lived for many years.
