Early this morning UK time David Cameron will step off a plane and set foot in a country no British Prime Minister has visited for more than six decades.
He arrives in Burma - the last and most significant stop on his five country tour of Asia.
No British leader has been here since the country secured independence from Britain in 1948 and the Foreign Office are not sure if a British Prime Minister has ever been here.
It is also the first time a Western leader has met face to face with the Nobel Peace Prize Laureate Aung San Suu Kyi since the country held elections here after 50 years of military rule.
Aung San Suu Kyi's party, the National League for Democracy, won 43 of the 45 seats in by-elections at the start of this month. She is a Member of Parliament for the first time.
A few short years ago - that is something her supporters feared would never happen.
David Cameron flies first to the new capital of the country now known as Myanmar.
In Naypyidaw, he will meet President Thein Sein - the man credited with pushing through the reforms. David Cameron has told us he is seeking reassurances from him that Burma's initial steps on the path to democracy are genuine and irreversible.
It will be in the former colonial capital, Rangoon, where Mr Cameron will meet Aung San Suu Kyi - at the lakeside villa where she has been under house arrest for 15 of the last 22 years.
Burma has been the subject of talks with the leaders of neighbouring countries Indonesia and Malaysia - where David Cameron has spend the past two days.
The Malaysian Prime Minister has urged the EU to lift the punishing sanctions that it imposed on Burma in order to encourage further reforms.
David Cameron says he will consider that request. European sanctions are due to run out on 23 April and foreign ministers will have to decide wehther or not to renew them.
The Prime Minister has hinted he is in favour of dismantling some on the sanctions. He told us in Kuala Lumpur that Britain "should not be backwards in its response."
Britain wants greater involvement in Burma to stem to growing influence of China on the former British colony.
British businesses are also keen to start investing here - but Downing Street insists the business delegation which has accompanied him all week is not on a trade mission on this leg of the tour.
These are still very early days - but it seems this pariah state is now finally coming in from the cold.
