Amnesty International is withdrawn Aung San Suu Kyi of its highest honour, the Ambassador of Conscience Award.
The Myanmar leader accused of perpetuating human rights abuses by not speaking out about violence against the Rohingya Muslim minority, some 700,000 of whom have fled a military crackdown.
Once hailed as a champion in the fight for democracy, Aung San Suu Kyi has been stripped of a series of international honours over a Rohingya exodus that began in August 2017, and this is the latest honour in a string of awards Ms Suu Kyi, 73, has lost.
The international human rights group named Aung San Suu Kyi as its 2009 Ambassador of Conscience Award recipient when she was still under house arrest for her opposition to Myanmar's oppressive military junta.
In the eight years since she was released, Aung San Suu Kyi led her party to election victory in 2015 and set up a government the following year, but she has to share power with generals and has no oversight over the security forces.
Amnesty International said in a statement on Tuesday she had failed to speak out and had "shielded the security forces from accountability" for the violence against the Rohingya, calling it a "shameful betrayal of the values she once stood for".
The last time Ms Suu Kyi spoke to the BBC in April 2017, she said: "I think ethnic cleansing is too strong an expression to use for what is happening."
Her government claims it will begin to welcome back the first groups of refugees later this week as part of a deal with Bangladesh, which has alarmed the UN and aid agencies.
The UN refugee agency wants Rohingya families to be able to return to their former villages and decide for themselves if they feel they are able to live there safely and with dignity.
