New Zealand resident Darrell Read allegedly offered an English colleague "copious amounts of curry" in return for helping fix Libor rates, according to reports of his London trial.
Read is on trial with five co-accused for allegedly conspiring to manipulate Libor rates with the now-convicted trader Tom Hayes.
Libor - or London interbank offered rate - sets the price for banks, international financiers or anyone wanting to raise funds through the interest rate markets.
The accused group are former brokers of ICAP, RP Martin and Tullett Prebon and their trial began in the Southwark Crown Court in London this week.
The sextet - Wellington resident Darrell Read, Colin Goodman, Danny Wilkinson, Terry Farr, James Gilmour and Noel Cryan - are defending charges of conspiracy to defraud.
