Arguing on behalf of Vijay Mallya will be Queen's counsel Clare Montgomery, a lawyer with extensive experience in extradition and international criminal law.
Known to be fierce and a quick thinker, Ms Montgomery, 30, was described in a recent report by renowned legal firm Chambers and Partners as "'one of the finest minds at the bar".
Mr Mallya is accused of defaulting on loans amounting to Rs 9,000 crore, borrowed from different banks across India for his collapsed Kingfisher Airlines. The second charge being investigated by the Enforcement Directorate includes money laundering.
After a recent court hearing, Mr Mallya was asked whether he would "return the thousands of crore rupees that he owes banks". He answered, "You can keep dreaming about a million pounds without knowing the facts. You will hear everything in court, I will say whatever I have to in court."
Mr Mallya fled to the UK in March 2016. India filed a case seeking his extradition in February 2017.
Apart from pleading not guilty, Mr Mallya is expected to raise the poor condition of prisons in India as a reason why he should not be extradited.
