Extraditing two Indian brothers accused of orchestrating industrial-scale corruption to South Africa from Dubai where they were arrested last week could take years and lead to a costly legal battle, experts warn.

Business tycoons Atul and Rajesh Gupta, held on suspicion of fraud and money laundering, are alleged to have colluded with former president Jacob Zuma to bleed public funds from Africa's most advanced economy.
