Zelensky asks allies for fighter jets on UK visit

President Volodymyr Zelensky used a historic visit to London to urge allies to send combat aircraft to Ukraine and deliver "wings for freedom".

Britain said it would consider the proposal in the "long term", although the United States and other NATO allies remain wary of getting more embroiled in Ukraine's war with Russia.

Zelensky -- dressed in his usual green fatigues -- received waves of applause as he made a historic address to both the lower and upper houses of the British parliament, on what is only his second overseas trip since the war began.

"I appeal to you and the world... for combat aircrafts for Ukraine, wings for freedom," he said.

In London, Zelensky held talks with Sunak and also met with King Charles III and thanked him for his support of Ukrainian refugees.

British Prime Minister Rishi Sunak announced that the two have signed the "London Declaration" deepening their cooperation and that "the most crucial capability right here and now is main battle tanks" and long range missiles.

Speaking alongside Zelensky, Sunak said that "nothing is off the table" for Ukraine -- including fighter-combat aircraft.

"Of course they are part of the conversation," he said but held back from giving a concrete commitment to provide fighter planes.

Zelensky said that fighter jets had been discussed and reiterated his call for longer-range missiles.

Russia subsequently said that there would be a "response" from Moscow should Britain supply aircraft to Ukraine.
