The Bharatiya Janata Party has asked the Congress party to take necessary action against Punjab Chief Minister Captain Amarinder Singh who was photographed in a gurdwara in Canada [Images] with a 'Khalistan Zindabad' slogan in the backdrop.

Addressing a news conference in New Delhi, BJP general secretary Arun Jaitley said the number of statements issued by Singh as clarification has in fact further complicated matters.

• Canada controversy ridiculous: Amarinder

"The chief minister claims that the picture was taken at a gurdwara in Canada where he made an unscheduled stop. But the facts are contrary to his claim. He visited the gurdwara on May 15. Three days before he left, all the newspapers had printed his schedule and the visit to the controversial gurdwara was very much there," Jaitley said.

Jaitley wanted to know if Singh knew what was written in the background, why he did not distance himself from the inscription.

"He should have come down heavily on the inscription. The more he explains his position, the more he finds himself in a mess," Jaitley said.

Asked whether the BJP will demand Singh's resignation, Jaitley said, "We leave it to the Congress party to take a decision on that," he added.
