Senior British foreign service officer Robert Chatterton Dickson reached Dhaka on Sunday to take over his new responsibility as British high commissioner to Bangladesh.
Dickson is expected to present his credential to president Abdul Hamid this week, officials said.
Dickson was an additional director at the British foreign office when he was being appointed as high commissioner in Dhaka.
He joined the British foreign service in 1995 and discharged different responsibilities including as acting ambassador to Afghanistan and at National Security Secretariat and Counter Terrorism Department of the British Foreign and Commonwealth Office.
His predecessor Alison Blake left Dhaka last week after completing her service as high commissioner to Bangladesh for about three years.
