The Bharatiya Janata Party on Sunday did not rule out a bigger role for Gujarat Chief Minister Narendra Modi [Images], including at the national level.

"Politics does not accept any form of stagnation. Politicians, personalities evolve over a period of time. What will happen ten years down the road or five years down the road I don't know," senior BJP leader Arun Jaitley said in New Delhi.

"As far as a role for Modi in the national party is concerned, certainly he is one of our foremost leaders in the country. He has a great amount of charisma and he is there," Jaitley said.

However, Jaitley added: "But as of today, I am reasonably certain he is committed to the people of Gujarat. He has secured for the second time a very respectable mandate and therefore he is committed to serve the people of Gujarat."

There has been speculation that Modi is aiming at finding a bigger role for himself at the national level, including the Prime Minister's post if the BJP comes to power. Jaitley, who is party in-charge of Gujarat, said BJP's win can be attributed to Modi's immense credibility and added, "Modi provided the necessary edge to BJP's campaign."

Jaitley said the BJP was inherently strongly in Gujarat and had a sound organisational base in the state. Asked whether the BJP's showing in Gujarat would change the party's policies at the national level, Jaitley said a single victory and a possible victory in Himachal Pradesh would not lead to any changes but there would be a lot of resurgence in the party.
