Mumbai: Calling Manmohan Singh "a man of tremendous integrity and honesty", NCP chief Sharad Pawar today stood firmly behind the former Prime Minister and said that putting him in the dock in the coal block scam may affect the investment climate.

"The entire world knows Manmohan Singh and what he stands for. He is hailed as a man of tremendous integrity and honesty. And a person of his character being made to undergo this fate pains us all," Pawar told reporters here.
