Patel has written that he takes “this opportunity” to bring to Ahluwalia’s notice how the modernisation of Kolkata and Chennai airports is also being delayed due to “constant objections being raised by the Planning Commission about the scale and size of these airports”. These endless objections are holding up the project despite the fact that the Committee on Infrastructure headed by the Prime Minister has “categorically approved the projects”.

The minister winds off his letter rather sarcastically, saying he hoped the Deputy Chairman’s visits across Delhi and the country would draw his attention to “various problems of roads, electricity, water, sewerage system, public transport” and that he would address these problems in a “time-bound manner”.

Patel’s letter comes soon after Left leader Sitaram Yechury wrote to the PM on the issue of delay in the modernisation of Kolkata and Chennai airports and complained that “backdoor privatisation” of the 35 non-metro airports was being planned.
