He also dismissed the S&P's contention that India could be the first BRIC nation to falter and fall below investment grade in the ratings.
The S&P in its report said that the crux of the current political problem for economic liberalisation is the nature of leadership within the central government and not 'obstreperous' allies or an 'unhelpful' opposition.
"Slowing GDP growth and political roadblocks to economic policy making could put India at risk of losing its investment grade rating", the S&P said in its report --`Will India Be The First BRIC Fallen Angel?'
Standard and Poor's, which had lowered India's rating outlook to 'negative' from 'stable' in April, said the Congress party is divided on economic policies and there is substantial opposition within the party to any serious liberalisation of the economy.
In a strong statement, Mukherjee said the government is fully seized of the situation and expressed confidence that there will be a turnaround in the country's growth prospects in the coming months.
"This (S&P report) is not based on a fresh rating action ...Between April 2012 and now there are no significant events to indicate that the economy's vulnerability to shocks has increased, though the growth numbers for the fourth quarter 2011-12 have come below the expectations," he said. MORE
