A Communist MP in Russia's state Duma has been allegedly caught on camera romping with a prostitute in his parliamentary office.

Shocking footage of married dad-of-two Denis Parfyonov and the blonde callgirl shows the steamy session on a chair in front of his desk in Moscow.

The clip reportedly shows Deputy Parfyonov plying the curvy woman with what appears to be booze in a cup as they talk and laugh in his official office.

As they embrace, the 37-year-old deputy sits in a chair, and the woman sits on his lap.

Then, in front of his party's hammer and sickle flag, Parfyonov sits the adult worker down in the same chair and stands before her.

Finally, the lawmaker unzips the fly on his suit trousers and begins pulling down his black pants while she pulls her hair back, apparently preparing for oral sex.

Local media reports say Parfyonov and his English tutor wife Maria Lomakina married five years ago after meeting through the Communist party.

Footage of the romp surfaced first on social media but spread quickly to mainstream media by September 21.

Moscow MP Parfyonov was sanctioned by Western governments in 2022 for his support of Russia's invasion of Ukraine.

However, officials in the Communist Party of the Russian Federation have refused to comment on the clip.

The party's head of press relations in the central committee, Alexander Yushchenko, described the steamy video as having nothing to do with politics and being 'meaningless'.
