Kolkata: A war of words broke out between TMC and BJP on Sunday, hours before Narendra Modi took oath as Prime Minister for the third time.

While Kolkata Mayor and TMC leader Firhad Hakim predicted that the NDA coalition government would not last long, BJP leader Arjun Singh suggested that Hakim should be more concerned about his political future.

Singh, who was defeated by TMC in West Bengal's Barrackpore constituency, confirmed that he has received an invitation to attend Modi's swearing-in ceremony on Sunday.

Echoing the stance of party supremo and Chief Minister Mamata Banerjee, Hakim told reporters that the NDA government would be short-lived and termed the swearing-in as "temporary".

On Saturday, Banerjee had stressed that the India Bloc has not staked claim to form the government now, but that does not mean it will not do so later.

Speaking to reporters after the meeting of TMC MPs and senior leaders, Banerjee said her party would adopt a "wait and see" approach and expressed hope that the "weak and unstable" BJP-led NDA government would be removed from power. .
