'We're not going away,' Sunak warns Putin on support for Ukraine

Rishi Sunak has issued a warning to Vladimir Putin that "we're not going away" as world leaders at the G7 summit in Japan broadcast that they are not wavering in their support for Ukraine.

The Prime Minister said on Friday the Russian president needs to understand that Western allies are "steadfast" in supporting Volodymyr Zelensky's resistance against the invasion.

"My message to Putin is straightforward. We're not going away," Mr Sunak told Sky News during a round of interviews at Hiroshima's Seifukan tea house shortly before the summit was due to kick off.

Having signed a new defence and security pact with Tokyo, Mr Sunak will visit the A-bomb dome ruin with his Japanese counterpart, Fumio Kishida, to reflect on the atomic devastation in the Second World War.

Talks between G7 allies, including US President Joe Biden and France's Emmanuel Macron, will centre on military and economic support for Ukraine as they seek to show a united front.

"Russia needs to know that we and other countries remain steadfast in our resolve to support Ukraine, not just in the here and now with the resources it needs to protect itself, but for the long term as well," Mr Sunak told Sky.

"They can't just outlast us in this conflict," he added to ITV News.

"One of the common topics of conversation I'll be having and have been having with my fellow leaders is about the longer-term security agreements that we put in place in Ukraine, to deter future Russian aggression."

The UK is also preparing new individual sanctions against 86 people and companies to apply further pressure on the Russian president and his supporters.

The diamond export industry was worth more than £3bn to Russia in 2021, but No 10 conceded direct imports have been low since the UK-sanctioned state-owned miners Alrosa last year.

Britain’s move will add pressure on any hesitant allies to follow suit.

"I'm hopeful and confident that our partner countries will follow as they have done when we've done this previously, that will make the sanctions more effective, ensure that Russia pays a price for its illegal activity."

The three-day summit – also including Germany, Italy and Canada – will also include talks on economic stability and the security of Taiwan in the face of Chinese aggression.

"Guarding against economic coercion is something that the Prime Minister is pushing for," Mr Sunak's official spokesman said.
