Hundreds of Russians were arrested on Sunday across 80 different cities as the biggest protests in five years swept the country.

Among the detained was Alexei Navalny, the Russian anti-corruption campaigner and opposition leader, whose investigation accusing the country’s prime minister of amassing property portfolio worth millions of pounds via questionable deals was the impetus behind the protests.

Dmitry Medvedev, who served as Russian president between 2008 and 2012, uses a network of charities run by close associates to hide his control of assets including mansions, yachts, and even a vineyard, Mr Navalny claimed.
