In a sharp response to Dr S Jaishankar's remarks on the Katchatheevu island row, senior Congress leader P Chidambaram questioned why the foreign minister is "doing a somersault" on the issue. Mr Chidambaram also said that Dr Jaishankar's journey from being a "suave liberal foreign service officer" to "a mouthpiece of the RSS-BJP" will be "recorded in the annals of acrobatic sports". The counter-strike came after Dr Jaishankar today doubled down on Prime Minister Narendra Modi's charge at the Congress over the island row. Quoting decades-old discussions in Parliament, the minister said the governments led by Jawaharlal Nehru and Indira Gandhi were indifferent to the island.
