Burmese opposition leader Aung San Suu Kyi is due to arrive in the UK, where she is due to meet members of the Royal Family and address Parliament.
Ms Suu Kyi will begin her tour at the London School of Economics later and is set to meet the Prince of Wales and Duchess of Cornwall later in the week.
It is part of a tour of Europe, her first since 1988.
The pro-democracy leader spent much of the last 24 years under house arrest in Burma. She was freed in late 2010.
Her two-week-long European trip - seen as another milestone for Burma's political progress - includes visits to the UK, Switzerland, France and Norway.
It is her second recent overseas trip, after visiting Thailand in May.
Her decision to travel has been seen as a sign of confidence in the government of President Thein Sein, who has pursued a course of reform since coming to power last year, in Burma's first elections in 20 years.
Earlier this month Ms Suu Kyi gave her Nobel Peace Prize speech in Oslo more than 20 years after being awarded the prize.
She chose not to travel to Norway's capital in 1991 to collect her prize in person fearing she would not be allowed to return to Burma.

In her Nobel lecture, Ms Suu Kyi said she heard she had received the prize on the radio and it had felt "unreal".
Winning the Nobel Peace Prize "made me real once again. It had drawn me back into the wider human community", she said.
Ms Suu Kyi also said Western support had contributed to changes in Burma.
She began her tour in Geneva, at the UN's International Labour Organization.
And she visited Ireland on Monday where she received the freedom of the city of Dublin and met U2 singer Bono.

Ms Suu Kyi will meet Prince Charles and Camilla the following day.
She will also address both Houses of Parliament on Thursday and meet Prime Minister David Cameron and Foreign Secretary William Hague.
Ms Aung San Suu Kyi is the daughter of Burmese independence leader Aung San, who was assassinated in 1947.
She became the leader of Burma's pro-democracy movement when, after living abroad for many years, she returned to Burma in 1988, initially to look after her sick mother.
She never left the country, fearing its military rulers would not allow her to return and was unable to receive her Nobel Peace Prize in person, or be with her British husband when he died in 1999.
