“Home Minister P. Chidambaram enjoys my full confidence,” Singh was quoted by broadcaster NDTV’s website as saying.

On Monday, several TV channels reported the powerful home minister had offered to resign, days after a document emerged suggesting he failed to stop a multi-billion dollar telecoms scam.

The scandal over the sale of 2G telecoms licenses at rock bottom prices in 2007 when Palaniappan Chidambaram was finance minister has damaged the government’s credibility and already landed one former minister and company executives in jail.

A finance ministry memo made public last week implied Chidambaram failed to rectify the underpriced sale of telecoms licenses that lost the treasury up to $39 billion. The note was approved by Finance Minister Pranab Mukherjee, considered by many to be a rival to Chidambaram in the cabinet.

“There are no dissensions in my cabinet,” Prime Minister Singh said on board a plane on his way back to New Delhi from the United States, NDTV reported.

“The opposition wants to force early elections. We will complete the full term,” Singh was quoted as saying.

Singh’s government was voted back to power in 2009 and completes its current five-year term in 2014.
