The CPS will be arguing on behalf of the Indian authorities when the fugitive businessman's extradition case comes up for hearing at Westminster Magistrates Court in London on June 13.
The hearing was earlier scheduled for May 17.
"The next hearing is June 13 for a case management hearing, a CPS spokesperson said today.
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.
