Grant Shapps has seized the first Russian superyacht in British waters as part of sanctions against the Kremlin.

The 58m (192ft) Phi, worth an estimated £38m, was barred from leaving Canary Wharf at midday.

Its ownership is “deliberately well hidden” but is believed to be linked to an unnamed Russian businessman. The Transport Secretary said the detention sent “a clear and stark warning to Putin and his cronies”.

Mr Shapps visited Canary Wharf on Tuesday to formally seize the vessel after an investigation between the Department for Transport, National Crime Agency and Border Force Maritime Investigation Bureau.

The yacht was first identified as potentially Russian-owned on March 13. It was planning to leave its east London mooring earlier on Tuesday. 

Its maiden voyage was from Ijmuiden in the Netherlands to London on Dec 10. It has remained in Canary Wharf since, according to the website MarineTraffic.

The yacht can accommodate up to 12 guests and boasts six staterooms. Built from aluminium, its Dutch shipbuilders said it has a swimming pool and infinity wine cellar.

Mr Shapps said: “Today we’ve detained a £38m superyacht and turned an icon of Russia’s power and wealth into a clear and stark warning to Putin and his cronies.
