"As the head of the Deputy High Commission in Chennai, Oliver's role will include promoting business and trade and also strengthening relationships between Tamil Nadu, Puducherry and the UK," it said.
Having joined the Foreign and Commonwealth Office in 2004, he has served in various portfolios including counter- terrorism, enery and climate change before joining the British Embassy in Brasilia, Brazil.
Later, he moved to the British Consulate General in Rio de Janeiro, where he was the political consul.
