Nursing national ambitions, Trinamool Congress chief Mamata Banerjee on Thursday took another swipe at BJP prime ministerial candidate Narendra Modi saying there was a difference between a ‘paper tiger’ and a Royal Bengal Tiger.

“Don’t they know that there is difference between a paper tiger and a Royal Bengal tiger. In Bengal there is a Royal Bengal Tiger in the Sunderbans,” Ms Banerjee, the Chief Minister told an election meeting here in Purulia district.

She also alleged that those who were divisive, caused riots and were racists could not constitutionally ascend to the Prime Minister’s chair.

“Those who cause riots between Hindus and Muslims and stoke racism and divide Bengalis and non-Bengalis have no right legally or constitutionally to sit in the PM’s chair,” Ms Banerjee said.

“The architects of the Constitution like Baba Saheb Ambedkar envisaged secularism to be an adhesive force for a multi-religious and pluralistic Indian society. Preamble of the Constitution says our Constitution is secular,” Ms Banerjee said.
