Dismissing criticism by Congress and Aam Aadmi Party that BJP was "running away" from facing fresh polls in Delhi, Upadhyay said his party was "fully ready" for election as it has continued to enjoy people's trust across the country.
"Certain decisions will be taken after government formation in Maharashtra. The political situation will be clear soon," Upadhyay told PTI.
He said announcement of bypolls by Election Commission to three assembly constituencies in Delhi does not mean that BJP was avoiding facing assembly polls in the city and maintained that it will get a clear majority in case fresh mandate is taken.
"By-election to three assembly seats is a constitutional requirement. It does not reflect BJP's views about assembly polls in Delhi. In fact, the Congress and AAP were not ready for polls," he said.
Sources in BJP said Rashtriya Swayamsevak Sangh (RSS) was not in favour of forming a government by BJP by "managing the numbers" and asked the Delhi leadership to prepare for fresh polls.
Upadhyay said BJP's victory in Maharashtra and Haryana have proved that party maintained its strong popularity among the masses and it was confident of people's support in Delhi too.
The Election Commission, yesterday, had announced bypolls on November 25 to three assembly constituencies -- Krishna Nagar, Mehrauli and Tughlaqabad -- which fell vacant after BJP MLAs were elected to Lok Sabha in the general elections.
A number of Delhi BJP leaders said majority of the party workers were fully prepared to face election again. A senior leader said the party should refuse even if Lt Governor Najeeb Jung invites it to form government.
