New Delhi, Jan 29: Sujatha Singh, who was removed from the post of the foreign secretary late on Wednesday night, was left "livid and upset", sources close to her said.
Singh was replaced with Subrahmanyam Jaishankar, the Indian Ambassador to the US, soon after the three-day visit of US President Barack Obama to India.
According to close quarters, the appointment of Jaishankar as the foreign secretary is an indication to Prime Minister Modi's intent to control the foreign affairs department.
Sujatha Singh, who took over in August 2013, was removed from the post seven months ahead of her scheduled retirement.
The last time the country saw the chief of the elite foreign service removed was in the late 1980s when the late Rajiv Gandhi was the prime minister.
Sources said Singh had refused to take several exit routes in the recent past and was also reportedly sidelined from addressing media briefings and also excluded from key talks, an NDTV report said.
The Congress criticised Singh's removal, saying it was an unceremonious action. Senior party leader and former Union minister Manish Tewari sought an explanation from the Modi government.
