Aymeric Chauprade, a French independent who was elected as part of the National Front but left in 2015, said criticism of the hiring amounted to “conspiratorial Russophobia”.
“The European Parliament has validated the contract and all procedures have been respected,” Mr Chapraude said.
Mr Chauprade is however a member of the European parliament’s foreign affairs committee and a subcommittee on security and defence – which has raised concerns about whether his employee will have access to sensitive documents.
He once described Russia as “the hope of the world against new totalitarianism” and has been public in his support for the country’s annexation of Crimea.
Staff members have free access to the parliament’s buildings, but trainees generally do not have access to confidential documents.
Petras Austrevicius, a Lithuanian MEP from the parliament’s Liberal group told the broadcaster Radio Free Europe, which first reported the story, that the hiring was “a very big shame on the face of the European Parliament”.
“I couldn’t believe that Kremlin keeps its hand in the pockets and heart of the EU institutions,” the MEP said.
Dmitry Peskov told reporters of his daughter’s placement: “This is a matter of a normal student and a normal practice. I wouldn’t want to comment further. It concerns my daughter. Not my work obligations or work”
Mr Chauprade added: “The European Parliament claims it is against racism but all your hear from its Europhile members is anti-Americanism jingoism and conspiratorial Russophobia.”
