In a further signal of uneasiness about Congress' chances in the general elections, the leader of a key party in the coalition government said on Monday the state polls amounted to a rejection of "weak rulers".
"People do not want weak rulers," National Congress Party (NCP) leader Sharad Pawar said.
"They want decisive and result-oriented leaders who will formulate policies for (the) poor and implement them," he said.
Manmohan Singh, the taciturn 81-year-old Prime Minister, has been widely criticised for the government's policy drift and a sharp economic slowdown, and for allowing corruption to spin out of control since he was appointed to a second term in 2009.
Adding to the Congress party's troubles, half a dozen of its own lawmakers called for a parliamentary motion of no-confidence over a decision to split the southern state of Andhra Pradesh into two.
If at least 50 members of the Lower House back their demand, the stage would be set for a trial of strength in which Congress would need the support of several parties to survive.
Aiyar's remarks came after the Congress Party’s disastrous performance by the Congress in the assembly elections held over the last month in Madhya Pradesh, Rajsthan, Chhattisgrh and Delhi.
"A break from governance would be a welcome break that could be used to refit the party as the nation's natural party of governance in the 21st century," the upper house lawmaker wrote in a column.
"The current and prospective electoral reverses for the Congress are thus Rahul's golden opportunity," he said, referring to the young scion of the Nehru-Gandhi dynasty and potential candidate for Prime Minister.
Aiyar's opinion was personal and not the party's view, said Congress spokesman Bhakta Charan Das, but agreed there was a need to analyse what went wrong.
"The party will definitely introspect and we must come out with a very good approach to revitalise ourselves," he said.
The Congress party's main opponent, BJP, was the clear winner in three states that held assembly elections and left its rival standing in the nationl capital.
The BJP has been boosted by the energetic campaigning of its charismatic candidate for Prime Minister, Narendra Modi, but also by voter fatigue with Congress after years of spectacular corruption scandals and stubborn inflation.
Aiyar said the growing strength of regional parties would make it hard for the BJP to form a stable coalition and predicted there would be new general elections by 2016.
"I am deeply convinced that, whoever forms the government in 2014, we will be faced with another general election by 2015 or 2016, at the latest," he said.
"Who can be even half-way realistic and expect the Congress to return to power?" Aiyar said.
