Moscow said on Tuesday the "politicisation of Interpol" was unacceptable after critics called on the global police body to reject a Russian candidate to lead the organisation.

"Today we are witnessing a foreign media campaign aimed at discrediting Russia's candidate for the post of Interpol president," interior ministry spokeswoman Irina Volk said in a statement. 

"We consider the politicisation of Interpol... unacceptable," she said.
