Minister of State (MoS) for External Affairs, VK Singh on Tuesday said beleaguered businessman Vijay Mallya will be brought back to India soon but the Centre cannot "fix the time frame".

Speaking to the media here ahead of the hearing on Mallya's extradition case at a London court, Singh said: "He is in the UK. There is a treaty between the UK and India, so they are examining documents. Once they decide, based on our documents or seek clarifications from us, based on that, we can bring Mallya back, but can't fix the time frame."

The Union minister said that the process of extraditing a person from foreign land is complex as a particular country's law takes supremacy.

Mallya, is out on bail after being arrested in April by Scotland Yard on a warrant by India. The Crown Prosecution Service (CPS) will argue the matter on behalf of the Indian government.

According to reports, a four-member team of CBI and Enforcement Directorate (ED) had visited London earlier this month to discuss Mallya's case with British agencies.

The former liquor baron, whose now-defunct Kingfisher Airlines allegedly owes more than Rs.9,000 crore to various banks, had fled from India to UK on 2 March 2016.
