HERO leader Volodymyr Zelenskis addressing Parliament in a surprise whirlwind visit to the UK - the first since Russia invaded Ukraine last year.
Mr Zelensky, dressed in his trademark olive-green top, was greeted by rapturous applause by the MPs and Peers in Westminster Hall after disembarking from a military transport plane at Stansted Airport, located north of London.
Downing Street said the surprise visit would see Zelensky meet the PM and visit Ukrainian troops before meeting King Charles at Buckingham Palace this afternoon.
It comes after Rishi Sunak announced plans to train Ukrainian pilots, paving the way for them eventually being able to fly sophisticated Nato-standard jets, a key request from Mr Zelensky.
Mr Sunak said: "President Zelenskyy's visit to the UK is a testament to his country's courage, determination and fight, and a testament to the unbreakable friendship between our two countries. Since 2014, the UK has provided vital training to Ukrainian forces, allowing them to defend their country, protect their sovereignty and fight for their territory."

"I'm proud the United Kingdom has played, again, a leadership role in this regard being one of the first countries to provide financial and technical support, putting investigators on the ground, we're shortly to be hosting a conference together with the Dutch.

Labour leader 'welcomes' PM's extra support for Ukraine

"We all support this work and the UK's role in the international drive to ensure that Ukraine has the weapons and the technology required to defend herself. Does he agree that continuing this international effort is the only way to ensure Putin's defeat?"
Rishi Sunak replied: "The House may not all be aware that actually we have continued to train Ukrainian soldiers because it's something that we have done for years before the conflict started and something that we should be very proud of.
"But obviously we've intensified those efforts, last year we trained 10,000 Ukrainian soldiers through Operation Interflex. This year the Defence Secretary announced that (in) last year we'll be training 20,000 Ukrainian soldiers in addition to the marines and air force pilots that I mentioned earlier.
He added: "This has been an international effort. One thing that is a mark of UK leadership in this particular area is that around a dozen other countries have all come here to the UK to take part in our training programmes to support Ukrainian soldiers.
"Many members from around this House will have visited in their constituencies that effort. It's something that's making an incredible difference on the ground and I know something that President Zelensky is incredibly grateful for."
PM faces calls to ban Wagner Group as a 'symbolic' gesture
The Prime Minister faced calls to ban the Wagner mercenary group as a "symbolic" gesture on the day of President Volodymyr Zelensky's visit.

"They are doing Putin's bidding carrying out atrocities against Ukrainians on a daily basis. So on this symbolic day will the Prime Minister finally commit to proscribing the Wagner Group, a crucial part of treating Russia as the rogue state that it is?"
Rishi Sunak replied: "We have taken a lead from the beginning of this conflict in sanctioning and taking action against those entities connected with the war effort in Russia and beyond.
"With regard to Wagner Group he will know that we have already sanctioned the Wagner Group in its entirety as well as taking specific action against particular leaders, as he will know.
"With regard to proscriptions, it is not something that we would routinely comment on in public, but rest assured we continue to keep all of the proscriptions that we have under review."
