New Delhi: Days after calling PM Narendra Modi a 'psychopath', Delhi CM Arvind Kejriwal has written to him over odd-even scheme.

The Delhi CM has sought PM Modi's cooperation to implement odd-even plan vehicle formula in the national capital.

Delhi government has already ordered shutting down of schools in the national capital for 15 days from January 1 during the trial period of odd-even vehicle formula and would run the school buses under the DTC fleet.

In a bid to tackle air pollution in the capital, the Delhi government has announced that vehicles with odd and even number plates will be allowed to ply on the city’s roads only on alternate days starting January 1 - for a short trial period to begin with.
