Boris Johnson is coming under pressure to seize the super yachts of rich Russian oligarchs that regularly sail in Scottish waters.
Huge vessels owned by foreign millionaires are a regular sight along the Clyde during the summer months as wealthy elites enjoy luxury cruises.
One yacht - the £59 million Ragnar - was moored in Greenock last summer and is understood to be owned by former KGB officer Vladimir Strzhalkovsky.
The luxurious boat - which boasts its own helipad - turned heads when it made its way up the Clyde on a cruise from Gibraltar last June.
And in 2017 Russian billionaire Alexei Mordashov’s £40million superyacht was moored in Govan.
The Lady M made waves as she anchored next to the Queen Mary at the Glasgow Science Centre.
Mordashov was Russia’s richest man with an estimated worth of $15.7billion and he also has close ties to Vladimir Putin.
Now one MSP has said the growing list of sanctions against the Russian Government should include pleasure craft such as the Ragnar.
It comes as UK Transport Secretary Grant Shapps today wrote to all UK ports asking them not to provide access to any Russian flagged, registered, owned, controlled, chartered or operated vessels.
Labour's Paul Sweeney said the Clyde should not be a "safe haven" for super yachts linked to the Kremlin.
The Glasgow MSP told the Record: "Although such obnoxious displays of wealth have often been revolting to many Scots it is now utterly unconscionable that the Clyde could be used as a safe haven for Russian owned superyachts, many of which are owned by oligarchs with close links to Putin and to the Russian state.
"At a time where the European Union has taken the lead by banning all Russian owned or registered aircraft from European airspace, the UK should take the same approach to other methods of transport including yachts and other marine vessels.
"Ultimately, we must make life as difficult as possible for these individuals, and that means restricting the ease with which they are able to travel, possibly in an attempt to evade sanctions."
Sweeney added: "With the violence in Ukraine looking set to intensify, all means of sanctioning and seizing potentially corrupt Russian assets in the U.K. must be considered.
"We cannot allow Scotland to be anything other than a hostile environment for those who have accumulated vast wealth via what can only be described as unscrupulous means."
Chris McEleny, an Alba councillor representing Greenock, said: "Although it may be easy to issue decrees banning these yachts from Greenock, there is a balance between what effect that would have on helping to end the war, versus the impact on our own local economy.
"Until peace is reestablished, I would call on the Government to ban super yachts with links to Oligarchs from entering the Clyde - and if they do berth in Scotland we should seize them in the hope these acts can at least continue to add our own bit of pressure on reaching a peaceful settlement through diplomacy."
Asked whether the UK will impound any yachts belonging to sanctioned Russians, the Prime Minister’s spokesman said: “We are looking at all aspects of this for any sanctioned individuals to make sure that they are cut off from the UK.
"Obviously, in this country we follow the rule of law.”
