"These sort of phrases should not be used," he said replying to a question about Sangma's remarks made yesterday in Mumbai.
Sharpening his attack on Mukherjee, Sangma had said Rashtrapati Bhavan was being used as a "dumping ground" for the "failed" former Finance Minister.
"The Raisina Hill is being used as a dumping ground for the failed Finance Minister," Sangma had said.
To a question on Sangma dubbing him as a 'failed' Finance Minister, Mukherjee said "whether I have failed or succeeded ... Surely posterity will judge. I will not comment on it."
