Both ruling Congress and main opposition Bharatiya Janata Party (BJP) on Tuesday welcomed social activist Arvind Kejriwal as he launched his political party here.
Congress Member of Parliament (MP) Rajeev Shukla said everybody has the right to ´oppose´ in a democracy and ´whoever enters politics, it is a good thing´.
However, he said public support plays a crucial role in case a person enters politics.
BJP leader Shahnawaz Hussain said everyone has the right to form a political party.
"The Indian Constitution has given us the right to form a political party and contest elections. So, it is a good thing," Hussain told reporters.
Yoga guru Baba Ramdev, however, criticized Kejriwal and said anyone could form a political party in a minute.
"Let them form the party...anyone can form political party in a minute. The main thing is how many supporters you get," Ramdev said.
"It is important to win more than three hundred seats," he said.
