Ukrainian President Volodymyr Zelensky will make his first visit to the UK, APA reports citing Mirror.
In a surprise visit, Mr Zelensky will meet Prime Minister Rishi Sunak and deliver an address to Parliament, a rare occurrence for a foreign leader.
The Ukrainian leader will also visit troops being trained in Britain, Downing Street said.
Mr Sunak announced plans to train Ukrainian pilots which would pave the way for them to be able to fly Nato-standard jets - a key request from Ukraine.
The Prime Minister said: “President Zelensky’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.
