The Trinamul Congress on Friday slammed the central government for the roof collapse at Delhi airport's Terminal 1, alleging that Prime Minister Narendra Modi's guarantee was "crumbling".

Civil Aviation Minister K Rammohan Naidu announced that an investigation has been ordered into the roof collapse that left one person dead and six others injured.

"A Glimpse into PM Modi's 'Guarantee': Crumbling under his lies," the TMC said in a social media post.

"The roof at Delhi Airport's T1 collapsed, ..... which Modi hastily "inaugurated" in March, despite its unfinished state, just for election optics,'' the TMC said in its X handle post.

Naidu also said a thorough inspection of the structure at the airport would be carried out.

Sources in the government said the roof that collapsed at Delhi airport's Terminal-1 (T1) was constructed during 2008-09 and that the work was contracted out by GMR to private contractors.

T1 has only domestic flight operations by IndiGo and SpiceJet. The airport -- which has three terminals T1, T2 and T3 -- handles around 1,400 flight movements daily.
