However, the British government said it acknowledges "the seriousness of allegations" against Mallya and was "keen to assist" the Indian government.
The UK government's response came nearly a fortnight after India made a request for the deportation of Mallya, whose Indian passport was revoked in a bid to secure his presence for investigations against him under the Prevention of Money Laundering Act 2002. There is also a non-bailable warrant issued against Mallya.
"At the same time the UK acknowledges the seriousness of the allegations and is keen to assist the Government of India. They have asked GoI to consider requesting mutual legal assistance or extradition," MEA spokesperson Vikas Swarup said.
