"If any country has to progress you cannot ignore infrastructure. Today, there is the Mumbai airport, it is an international airport. Today, it is important to expand it. Today, we have to give facilities beyond take-off and landing. Mumbai is a major international city, the economic nerve centre of the country. An economic centre needs an effective means of communication and if steps are taken to implement this, then to put impediments would not be right. If there is something wrong one has to intervene but one needs infrastructure," Sharad Pawar told NDTV in an exclusive interview.
