"We need to seriously introspect why we have failed (in by-polls in various parts of country) within 100 days of stupendous victory in national election," Sinha told reporters, reacting to results of bypolls today.
"How it happened? ...The poor results in the by-polls have certainly put us in anxiety," Sinha, second term BJP Lok Sabha member from Patna Saheb seat, said.
"It seems we are paying for the absence of these veteran leaders from the poll scene," Sinha popularly known as "Bihari Babu" said.
He disagreed with the age bar of 75 years and urged the party leadership to "relook" at the decision.
"A person generally enters into active politics at the age of 40-50 years and takes at least 10 years to mature... excluding people of 75 and above age and, including only youth, not much experienced in the team, does not look a good idea," Sinha said.
