Venezuelan president Nicolás Maduro may have one of the lowest salaries of any South American leader but is still estimated to have a fortune of $2 million.

Venezuela's cash supply has now fallen below $1 billion according to Bloomberg, and while the nation does possess 161.2 tonnes of gold, it is struggling to sell it as the Bank of England, which holds around a third of its gold reserves, has refused Venezuela access amid US sanctions against the South American country. In retaliation, Venezuela launched a lawsuit against the Bank in May 2020 following the Bank's decision not to accept Nicolas Maduro as Venezuela's leader. Venezuela lost the first case, but after it appealed the original ruling was overturned in October. Both parties go back to court for a third time soon...

Prayuth Chan-ocha was a military leader who became prime minister of Thailand in 2014 after leading a successful coup. That year, figures released by the country's anti-corruption agency showed he had assets of more than $3.1 million, including a 2011 Mercedes-Benz S600L, a 2009 BMW 700Li, three Rolex watches and more than a dozen handguns.

While the exact figure is not known, it has been estimated that British prime minister Boris Johnson is worth about $4 million. The UK's  leader recently sold his former marital home that he shared with his ex-wife Marina Wheeler for £3.7 million ($4.8m) and has since bought a £1.3 million ($1.5m) townhouse in south London with his new wife Carrie Symonds. In the year before he became PM in July 2019, he earned £829,255 ($1.1m) according to investment house AJ Bell, which included a reported $357,000 (£275,000) a year as a columnist for newspaper The Daily Telegraph. Now he takes home a total salary of £157,372 ($219k), made up of £75,440 ($105k) for the role of Prime Minister, alongside his Parliamentary salary of £81,932 ($114k).

President Joe Biden took on the top job in January this year, and following financial disclosures his wealth has been estimated at $8 million.

Forbes suggest that even with tax, which would have reached $7 million and charity donations totalling $1.3 million, as well as reported household costs of $180,000 and mortgage interest reaching $80,000, his net worth should be higher. But it has been suggested that Biden may have given money to his family, or simply just spent it.

Paul Kagame has been president of Rwanda since 2000, after he led rebel forces to end the Rwandan genocide that saw more than a million people murdered. Kagame has been key to the African country's economic rehabilitation, which earned it the moniker of being the "Singapore of Africa", although this has been matched by an intolerance for dissent. In 2012 it was reported that Kagame and the Rwandan Patriotic Front are controlling the country’s economy through a holding company called Crystal Ventures, a group that has assets of $500 million across everything from private jets to the country’s biggest milk processor.

Gabon's president Ali Bongo Ondimba is said to be worth a cool $1 billion, despite reportedly only making $65,000 a year. Rights groups in the country have long accused Ondimba of looting the country of its oil and natural resources to create his fortune. In 2009, Transparency International filed a case against his family and the ensuing corruption enquiry discovered assets including 39 properties in France and nine luxury cars, but the case was dropped in 2017. A year later, it was reported that he spent $111 million on a 14-bedroom mansion in Paris.

Czech president Andrej Babiš was an agricultural magnate prior to winning office in 2017 and has an estimated net worth of $3.7 billion, according to Forbes. Often known as the "Czech Donald Trump", Babiš has styled himself as a self-made businessman who is fed up with corruption in politics. But in 2019 thousands of Czechs took to the streets to call for his resignation due to alleged conflicts of interest involving his former business and a criminal inquiry into fraud relating to EU subsidies. This month the issue has come to a head after Members of the European Parliament (MEPs) voted to commence proceedings against Babiš for a potential breach of EU law involving an alleged conflict of interest in Agrofert, the agriculture conglomerate he founded.

North Korean dictator Kim Jong-un has been estimated to have a net worth of $5 billion since 2013.

Quite a lot of mystery surrounds the finances of Russian president Vladimir Putin, but an estimate by former Hermitage Capital Management CEO Bill Browder given under oath to the US Senate Judiciary Committee in 2017 put the former KGB officer's net worth at a huge $200 billion. That's considerably higher than the net wealth of the world's richest person, Amazon founder Jeff Bezos. However, in 2018 the Central Election Commission of the Russian Federation said that Putin had officially only earned $673,000 between 2011 and 2016. It also revealed he had an apartment in St Petersburg and 230 shares in Bank St Petersburg. A recent video created by opposition leader Alexei Navalny (who is currently imprisoned in Russia) features an opulent palace by the Black Sea that was allegedly financed by billionaires close to the President as a "bribe". Navalny also alleges that Putin is obsessed by money and plotted to steal the nation's wealth. But in January this year Putin denied that the palace belonged to him and described the video as a "compilation and montage".
