"The UK Home department on February 21 conveyed that the request of India for extradition of Mallya has been certified by the secretary of state and sent to the Westminster Magistrates' Court for a district judge to consider the issue of releasing of warrant," External Affairs Ministry spokesperson Gopal Baglay said.
The development is a step forward towards securing the extradition of the fugitive businessman wanted in India for loan default of over Rs 9,000 crore.
Mr Baglay also noted that a formal extradition request in respect of Mr Mallya as per Extradition Treaty between India and the UK was handed over to the British High Commission here through a note verbale on February 8.
Earlier in January this year, a CBI court had issued a non-bailable warrant against Mr Mallya in the Rs 720-crore IDBI Bank loan default case.
Mr Mallya, whose now-defunct Kingfisher Airlines owes more than Rs 9,000 crore to various banks, had fled India on March 2, 2016.
