The senior-most woman parliamentarian has taken the new responsibility as yet another "challenge" in her long political career spanning over three decades.
"Every new responsibility is a challenge for any human being. For me making first 'roti', contesting first election were also challenges and now I have this new responsibility which the party has given me," Mahajan told PTI in an interview.
The 71-year-old Indore MP created history last month by becoming the first woman MP to have won eight times in row from the same Lok Sabha constituency. She defeated Satyanarayan Patel of Congress by a margin of 4,66,901 votes, highest in Madhya Pradesh.
Gearing up for the new responsibility, Mahajan said that she will try her level best to fulfil the expectations.
"The most important thing is that almost all other parties have supported it (her candidature). I will try my best to fulfil the expectations," she told PTI in an interview.
Her priority, she said, will be to create and maintain coordination among all the parties.
"Let's see what happens in future... But the first thing will be to develop co-ordination among all," said the veteran BJP leader.
There have been regular disruptions in Parliament in previous sessions and considering her soft-spoken nature, won't it be a challenge for her?
"There have been many reasons for disruptions in Parliament. I don't want to talk about them now....
"You have seen when Parliament proceedings were disrupted and you will see if the proceedings are smooth in future," said Mahajan, adding she will handle things in her own way.
Fondly called 'tai' (elder sister in Marathi), she said she will be like a mother, who loves her kids and scolds them as well when needed.
"I am also a mother and I have a heart of a mother so I will handle every situation like that," said Mahajan, who is a law graduate and has a Master of Arts degree from Indore University.
