Moily told Jaitley that the additional responsibility "dents" his image as the Finance Minister.
"It is just like a structural engineer doing the work of interior decoration also. You have to speak for the Government also. I do not think that a Finance Minister can be espoused to this kind of a post.
"Being an elder person than you, I think, I have a moral right to say that. The Finance Ministry requires total focus and total attention. It may be that sometimes, you should be really serious...," Moily said participating in a debate on supplementary demands for grants in Lok Sabha.
"It is all right. He has given up Defence portfolio. But taking over I&B will dent your image as a Finance Minister. This is my advice...," Moily said.
"It is a colorful job, no doubt. We want you to be colourful. But by being a good and sound Finance Minister, you can really be colourful. This is one thing which I would like to say here," he said.
Jaitley, who also holds the finance portfolio, was given the charge of the information and broadcasting ministry in a cabinet reshuffle last month.
