Dubbed the 'Beverly Hills of Britain', a secluded estate in Surrey is now under the magnifying glass because of its connections to Russia.
Ever since war broke out in Ukraine last year, scrutiny over Russian money in the UK has intensified and questions are being asked about the influence on London.
After the Soviet Union broke up in 1991, oligarchs became rich by seizing state assets in the form of oil and gas reserves in cut-price deals and moved their money to the UK.
It was once seemingly a mutually beneficial relationship, but now Putin's invasion of Ukraine has caused a problem and led the UK government to sanction a number of billionaires with ties to the Russian President.
Russian oligarchs living in the UK have "nowhere to hide", according to Home Secretary Lizz Truss, who has compiled a 'hit list' of individuals to target.
One place that is definitely under the spotlight is St George's Hill in Elmbridge, just outside Weybridge, where the amount of rich Russians is now causing tension.
The heavily guarded 964-acre estate is home to a greater concentration of rich Russians than Belgravia's Eaton Square, which had often been nicknamed 'Red Square'.
Prices have soared in the last year and houses regular change hands for up to £20 million - with manicured lawns, golf course and round-the-clock security.
It is one of the country's most sought-after private estates and more than a third of the homes are valued at seven figures.
It was once home to a number of well-known celebs including John Lennon, Ringo Starr, Tom Jones, Kate Winslet, Elton John and Cliff Richard.
More than a quarter of the 430 luxury homes are said to be owned by Russians and those from former Soviet states, but there is no evidence any of the people named on the sanction list live here.
There was a big influx of Russians during the 200s after the introduction of the 'golden visa' scheme, where the wealthy could come here if they invested at least £2m.
Russian billionaire residents there have included Oleg Deripaska, a target of U.S. sanctions, and Boris Berezovsky, a onetime ally-turned-enemy of President Putin who died in 2013.
They are all protected by several tiers of electronic gates and access has to be granted through a special one manned by staff.
One of the security guards told The Guardian that there are more Russians living there now than he has seen in six years working on the gate.
"I imagine they are getting a bit nervous now about what Boris [Johnson] might do now that Putin has invaded Ukraine," he said, adding that they would not speak to journalists.
Round the corner in a nearby council estate, 75-year-old Joy had her say on "all those bloody dodgy Russians next door".
She said: "I think they should all be turfed out of the country. Why should they be allowed to live here when there is a war going on over there. The only way to stop Putin is to put pressure on Russians.
"The rich Russians who live in the huge houses over there, the government should seize their houses."
Earlier this week, Boris Johnson blasted the "inexplicable silence" of oligarchs who have not condemned Vladimir Putin.
He told ITV News: “I think that their silence is inexplicable, and I think that people need to step up and denounce this act of aggression, and those oligarchs who have connections with the Putin regime and who are benefitting from their association with the Russian state, we are going to expose and distrain their assets.”
Deputy Prime Minister Dominic Raab said sanctions against Russia will cause oligarchs to apply pressure on Vladimir Putin and show the cost of war to the Russian people.
After discussing the measures against the Russian central bank, Mr Raab told BBC Breakfast: "That will starve Putin's war machine and will also put pressure on many of the oligarchs who need access to the international system and who will apply pressure on Putin.
"I think it also shows the Russian people at large - and we're certainly not targeting them - but it's inevitable that Russia's and Putin's misadventure, his catastrophic decision, will be disastrous for the Russian people. It will show them the economic cost to them of getting bogged down in this unwarranted, unjustifiable war."
One person who is being called to lead the charge against Putin is Chelsea owner Roman Abramovich.
Abramovich bought Chelsea for just £140million in 2003 and has pumped more than a £1bn into the club since, establishing them as one of the best teams in the world, but now there are calls for him to sell the club.
The Russian-Israeli billionaire handed "stewardship and care" of Chelsea FC to the club foundation’s trustees on Saturday and his spokesperson confirmed he is attempting to broker peace between Russia and Ukraine.
“I can confirm that Roman Abramovich was contacted by the Ukrainian side for support in achieving a peaceful resolution, and that he has been trying to help ever since,” Abramovich’s spokesperson said.
But the spokesperson added: “Considering what is at stake, we would ask for your understanding as to why we have not commented on neither the situation as such nor his involvement.”
After the statement, Labour MP Chris Byrant hit back in a tweet this morning: "He should simply condemn the criminal invasion.”
Asked if Abramovich, like some other oligarchs, should denounce Putin and his actions, Mr Raab replied: "I think every right-thinking person should denounce what Putin has done, not just as catastrophic for Ukraine and European security, but as catastrophic for ordinary Russians.
"And when you see the doubling of interest rates by the Russian Central Bank to 20%, you can see what we mean by that."
