As the year mark for Russia's conflict approaches, it is time to step up support for Ukraine, according to the UK PM.

British Prime Minister Rishi Sunak called on world leaders Saturday to ``double down'' on support for Ukraine, saying additional arms and security guarantees are needed.

As the year mark for Russia's conflict approaches, it is time to step up support for Ukraine, according to the UK PM.

Rishi Sunak, the British prime minister, urged world leaders to "double down" on their support for Ukraine on Saturday, arguing that more weapons and security assurances are required to shield the region from Russian aggression both now and in the future.

In a speech to the Munich Security Conference, an annual gathering of heads of state, defence ministers, and other world leaders, Sunak conveyed the message. Over a year after Russian forces invaded Ukraine, the conference this year is concentrated on dangers to the established norms of international relations.

Highlighting Britain’s recent commitment to provide battle tanks, advanced air defense systems and longer-range missiles to Ukraine, Sunak urged other nations to follow suit before Russia launches an expected spring offensive.

“Now is the moment to double down on our military support,” Sunak said. “When Putin started this war, he gambled that our resolve would falter. Even now he is betting we will lose our nerve.”

Sunak also called on NATO to provide long-term security guarantees for Ukraine. Such commitments are necessary to shield Ukraine from future Russian aggression and to protect the system of international rules that have helped keep peace since the end of World War II, Sunak said.

“It’s about the security and sovereignty of every nation,” the prime minister said. “Because Russia’s invasion, its abhorrent war crimes and irresponsible nuclear rhetoric are symptomatic of a broader threat to everything we believe in.”
