Delhi Chief Minister Arvind Kejriwal on Tuesday met Minister for Road Transport Nitin Gadkari and urged him to back the second phase of the odd-even traffic scheme aimed at battling pollution.

Kejriwal, accompanied by Transport Minister of Delhi Gopal Rai, also urged Gadkari to extend the date for registration of e-rickshaws by six months. The last date for registration was March 31, an official said.

"The chief minister discussed several issues with Gadkari including odd-even and extension of date for registration of e-rickshaws. He also sought Gadkari's support to improve the traffic situation in (Delhi)," said the official.

The official added that Gadkari assured "full support" to the Delhi government in the fight against pollution.
