Foreign Secretary James Cleverly writes for The Express.

When our Ambassador in Ukraine visited a Kyiv market recently, she discovered even the socks on sale had joined the struggle against Russia's invasion. Melinda Simmons found countless pairs emblazoned with choice insults aimed at Vladimir Putin, while others carried the simple phrase: "British Intelligence".

This was a wry tribute to British Defence Intelligence, which has won a large following in Ukraine by publishing its daily assessment of Russia's invasion. The scene provided yet more evidence of how Ukraine's heroic people are defying Vladimir Putin's onslaught as free countries unite in their support.

These were also the themes of the meeting of G7 Foreign Ministers that I have just attended in the German city of Munster: standing up to the aggressor and standing united.

We all know Putin has suffered one defeat after another in Ukraine. Now he is taking revenge by firing cruise missiles and suicide drones at Ukrainian cities, depriving millions of electricity and often water.

Meanwhile, he is doing his best to drive up and destabilise global food and energy prices. By resorting to these cynical tactics, Putin has made his war everybody's business.

His exploitation of the Grain Initiative, which allowed 100,000 tonnes of Ukrainian food to be exported every day, is a case in point.

Last Saturday, Putin said he was suspending Russia's participation in the initiative. By Wednesday, he was back in again.

He created uncertainty and risked the progress made for desperately hungry people.

Putin's tactics are not only abhorrent futile because Britain and our allies are going to stand with Ukraine whatever he does.

My fellow G7 foreign ministers were steadfast in our support. As an alliance of friends, we are determined to show strategic endurance and press on until Ukraine prevails.

In Germany, I met the Foreign Ministers of Ghana and Kenya to discuss global hunger and our shared efforts to tackle climate change, respond to humanitarian crises and strengthen the production and trade of food across the African continent.

Putin is also trying to destabilise the countries of the western Balkans.

At an earlier summit in Berlin, I met our friends in that region and discussed how Britain can support their efforts to reduce reliance on Russian energy and strengthen cyber security.

Britain will always be an honest and reliable partner, steadfast in our defence of freedom, democracy and development.

As Putin attacks Ukraine, using tactics that leave the world’s most vulnerable people further exposed to the global food crisis, we will not be silent, and nor will our friends among the free nations.
