The last letters that Gordon Brown wrote from inside No 10 were to Nelson Mandela and Aung San Suu Kyi. A friend of the former prime minister said that they are "two prisoners of conscience and two people who have inspired him hugely".
Here are his words to the Burmese leader.
This is one of the last letters I write as Prime Minister and I want it to be to you, to champion your cause for democracy in Burma and to say I will do everything I can to support you. You are, for me, what courage is and I will fight for you to be free and your people [to be] free.
