Volodymyr Zelenskyy has received a standing ovation and cheers as he began his historic address to parliament during a surprise visit to the UK.
The Ukrainian president is the first foreign leader to address parliamentarians in Westminster Hall, the oldest part of parliament, since former Myanmar leader Aung San Suu Kyi, who is now in jail, in 2012.
Wearing his usual outfit of military fatigues, Mr Zelenskyy entered the famous hall to a standing ovation and cheers from parliamentarians.

He said: “We will always come out on top of evil.
“We know freedom will win. We know Russia will lose.”
He thanked “all the people of England and Scotland, of Wales and Northern Ireland” for their support, on behalf of “our workers who are now in the trenches under enemy artillery fire”.
Former prime minister Boris Johnson, who has a close relationship with Mr Zelenskyy and has been one of Ukraine’s most vocal backers, was spotted in the crowd of politicians.
The Ukrainian president arrived in the UK just before 10.30am on an RAF plane at Stansted Airport, where Prime Minister Rishi Sunak greeted him.
Both leaders travelled to Downing Street in a cavalcade before they entered Number 10 to clapping from behind the doors for the president and his sizeable security detail, something usually only reserved for a new prime minister.
After entering No 10, Mr Zelenskyy thanked Britain for its “big support from the first days of full-scale invasion” and said his country has “very good relations with Rishi”.
The visit is only Mr Zelenskyy’s second visit outside Ukraine since Russia invaded last February. He travelled to the United States just before Christmas and stopped off in Poland on the way back.
Mr Zelenskyy is set to meet King Charles at Buckingham Palace this afternoon and will visit also Ukrainian troops training in the UK.
Moments after Mr Zelenskyy arrived, the UK imposed further sanctions on companies supplying equipment to Russia for the war and Russians connected to “nefarious financial networks”, helping the Kremlin elites maintain wealth and power.
Mr Sunak is set to discuss further support for Ukraine through more equipment and training.
