A four-member joint CBI and Enforcement Directorate (ED) team had arrived in London earlier this month.
"Our aim is to build a strong, infallible case and these meetings will help resolve issues across the table. The CPS will be arguing based on documents provided by CBI and ED, therefore a joint team is here to address queries they may have," official sources had said.
Mallya, the 61-year-old chief of the erstwhile Kingfisher Airlines who owes over Rs 9,000 crore to various Indian banks, has been living in self-imposed exile in Britain since March last year.
He was arrested by Scotland Yard last month on fraud allegations, triggering an official extradition process in the British courts.
He attended a central London police station for his arrest and was released on conditional bail a few hours later after providing a bail bond worth 650,000 pounds, assuring the court of abiding by all conditions associated with extradition proceedings, such as the surrender of his passport and a ban on him possessing any travel documents.
