Prime Minister Manmohan Singh Monday returned to his South Block office after being unwell for almost a week, an official spokesman said.

'The prime minister was not well,' the spokesman told IANS.

But even at his 7 Race Course Road residence, Singh met cabinet colleagues and senior officials to discuss the row with the Left on the India-US nuclear deal and efforts to check rising food prices.
