Kyaw Zwar Minn has previously alleged the embassy was “seized” by a military attache in an “unacceptable and disrespectful” act against Myanmar’s people and the UK.
The diplomat had called for the release of Aung San Suu Kyi, Myanmar’s elected leader who was detained in the wake of the military seizing power in a coup on February 1.
The coup has led to weeks of protest and a retaliation from the regime resulting in hundreds of deaths.
Mr Minn said he spent the night in his car having been locked out of the embassy in Mayfair, central London, last Wednesday.
He told The Guardian his former staff delivered a letter ordering him to move out by Thursday.
Speaking to the paper, he said: “Some friends and relatives, they are hiding, staying away from their places. They are not able to show their face in public because of me.
“The Foreign Office said that if they invaded our residence the British police could not do anything.
“People are watching very closely the British government’s next step. They got a lesson from the Myanmar army ... now they have to give a lesson back to the army. They have to show their strength.”
The UK has made an offer of safe haven to the ambassador.
