NEW DELHI - Prime Minister Manmohan Singh Tuesday visited the All India Institute of Medical Sciences (AIIMS) for an overall medical check-up.

Manmohan Singh is undergoing diagnostic tests that will be completed Wednesday, the Prime Minister’s Office (PMO) said in a statement.

The check-up forced Manmohan to cancel his visit to Kolkata, where he was scheduled to inaugurate Wednesday the 150-year celebrations of the St. Xavier’s College.
