Dozens of protesters are demonstrating outside the Dorchester Hotel in central London against Brunei's anti-LGBT laws.
Many of the protesters were carrying placards and banners calling for homophobia to be stamped out as well as rainbow flags.
Barriers had been put up around the front of the hotel in Park Lane.
More than 100 people lined the streets around the hotel, chanting and holding up signs.
Piles of rainbow-coloured stones had been laid on the pavement
Ashleigh Gonsalves, who was at the demonstration with her wife and carrying a rainbow umbrella, said the protest was very important.
She added: "I am married to a woman so it touches home.
"It's very important, it's about lives, it doesn't get more important than that."
Protesters spilled off the pavements and into the roads
Ahead of the demonstration the University of Oxford said it would reconsider its decision to award an honorary degree to the Sultan.
In a statement on Saturday, the university said it shared the "international revulsion" of the laws and that the decision to confer the honorary degree of civil law by diploma to Sultan Hassanal Bolkiah in 1993 would be reconsidered through its "established process".
But it stressed no one had the right "summarily to rescind it" and added: "We also believe in due process. Just as nobody has a right to confer an honorary degree, nobody has a right summarily to rescind it.
"The decision to confer this degree 26 years ago was recommended by a committee and approved by council and by congregation at the time.
"We will reconsider this decision through our established process in light of the information now available, as other British universities are doing."
Human rights activist Peter Tatchell, who led the protest, said if the Sultan did not revoke the laws the British Government should sever all ties with the regime.
He added: "If the Sultan will not listen to reason and compassion we believe the British Government should sever all diplomatic, economic and military ties with the regime.
"What is shameful is that our royal family puts royal ties before human rights."
There were cries of "shame" from the crowd when Mr Tatchell said the royal family were not going to sever ties with the regime.
