Russian-born Durov is currently under judicial supervision in France, holed up in Paris’ glitzy Crillon hotel after being placed under formal investigation for alleged organised crime on Telegram.
He said it was there that Lerner, who leads the DGSE foreign spy agency, approached him.
“This spring at the Salon des Batailles in the Hôtel de Crillon, Nicolas Lerner, head of French intelligence, asked me to ban conservative voices in Romania ahead of elections. I refused,” Durov wrote on X late on Sunday.
“We didn’t block protesters in Russia, Belarus, or Iran. We won’t start doing it in Europe.”
The centrist mayor of Bucharest, Nicusor Dan, won Romania’s presidential election yesterday in a shock upset over George Simion, a hard-right, nationalist rival who had pledged to adopt a path inspired by US President Donald Trump’s politics.
The Romanian result was a relief for centrist policymakers in Brussels where there is concern that popular anger with mainstream elites over migration and cost of living pressures could bolster support for far-right parties and erode unity on the continent over how to deal with Russia.
France’s DGSE said in a statement its officials had indeed met with Durov various times over the years “to firmly remind him of his company’s responsibilities, and his own personally, in preventing terrorist and child pornography threats”.
However, the DGSE “vigorously refutes the allegations that requests to ban accounts related to any electoral process were made on these occasions”, it said.
Musk takes note
Durov’s accusation was reposted on X by US billionaire Elon Musk, one of various powerful figures on the US right who have accused European nations of suppressing far-right voices.
“Wow,” Musk wrote.
Durov had earlier yesterday said he had refused a request by a western government to silence conservative voices ahead of the Romania run-off vote.
“Telegram will not restrict the freedoms of Romanian users or block their political channels,” Durov said, adding an emoji of a baguette that implied it was France.
The French foreign ministry denied any such interference and called on all to “exercise responsibility and respect for Romanian democracy”.
The arrest of Durov last year ignited a debate about free speech online.
Musk, who criticised the arrest of Durov, is also being probed by French prosecutors over alleged algorithmic bias on X.
Musk has used X to personally support right-wing parties and causes in countries including Germany and Britain, leading to concerns about undue foreign interference.
