Russia's ambassador to the Organization for Security and Co-operation in Europe was told 'it will not work' in Vienna on Thursday, as the UK issued a blunt four-word warning in response to Russia's latest 'sleep well' threat over the Ukraine conflict. British envoy Neil Holland used the OSCE meeting to insist the UK 'will not be deterred' from supporting Ukraine, directly answering recent Kremlin rhetoric aimed at countries arming Kyiv.

The news came after senior Russian official Dmitry Medvedev, a former president and now deputy chairman of Russia's Security Council, told Western leaders thatEuropean facilities producing drones and other equipment for Ukrainewere 'potential targets' for Russian forces. Medvedev, who has become one of Moscow's most aggressive public voices since the full-scale invasion began in 2022, ended his warning with a pointed sign-off to European governments: 'Sleep well, European partners!'

Russia has repeatedly accused the West of escalating the Russia-Ukraine conflict by supplying weapons, ammunition and training to Kyiv. Western governments, including the UK, frame their role very differently, arguing that Ukraine is exercising its right to self-defence against what they call an illegal and unprovoked invasion.

In his statement to the OSCE, Holland said Russia's latest language at the Vienna gathering reflected 'a familiar attempt to intimidate and deter those who support Ukraine's right to defend itself.' He criticised what he described as Russia's 'disregard for agreed rules,' accusing Moscow of trying to recast its own offensive war as a defensive response to NATO and EU policies.

'The Russian state characterises international support for Ukraine's defence against its deadly attacks as an escalation of the conflict,' Holland said, according to remarks reported by theExpress. 'A claim that is unfounded and aimed at deflecting from its own actions.'

His four-word retort — 'It will not work' — was aimed squarely at Medvedev's earlier suggestion that European arms and drone production lines could be hit. Coming in the formal, often restrained setting of the OSCE, it amounted to an unusually terse and personal pushback.

Holland went on to underline that the UK sees its Ukraine policy as both legal and necessary. 'Our support for Ukraine, and readiness to defend ourselves, is lawful and necessary in response to Russia's continued aggression,' he told fellow delegates.

He then delivered the UK's clearest line of the day: 'The UK will not be deterred. The UK will continue to provide the military assistance Ukraine needs, for as long as it needs it.'

Since Russia's full-scale invasion in 2022, Britain has been one of Kyiv's most active backers, supplying air defence systems, armoured vehicles and long-range missiles, as well as training Ukrainian troops on UK soil. London has regularly presented that support as a test of European security more broadly, arguing that allowing Russia to succeed would embolden further aggression.

I welcome today’s decisions to move forward with the €90 billion EU loan for Ukraine and adopt the 20th sanctions package on Russia.
