Second round of resignation in three months
The news comes also three months after the company's chief internal audit and risk assurance director resigned. Cairn, however, sought to downplay the resignations saying that they were unconnected and part of a "natural evolution" in any organisation.
"Such movements are part of a natural evolution in any organisation and are in line with career aspirations and personal priorities of individuals. Having a strong and healthy leadership pipeline is the key in a high-growth organisation like ours. We want to emphasise here that these movements are unconnected and have been spread over a period of time," Cairn said in an official statement.
