A war of words has erupted between the Aam Aadmi Party (AAP) MP Sanjay Singh and the Bharatiya Janata Party (BJP) MP Gautam Gambhir after the latter called Delhi Chief Minister Arvind Kejriwal a "hypocrite CM".

Gambhir's statement drew a sharp reaction from AAP MP Sanjay Singh who accused Gambhir of opposing freebies being provided to the poor while himself availing of "free facilities". "If Gautam Gambhir is against free services which benefit the poor, he should surrender the free facilities including 50,000 units of electricity that an MP is entitled to. This is sheer display of hypocrisy" he said.

Refuting the claim, Gambhir tweeted: "I have NEVER said that POOR should not get free services. Only that people who CAN afford should be charged a nominal amount!! FYI - I have not taken a single govt benefit in 8 months unlike your hypocrite CM who had been advertising himself at the taxpayers' expense for 5 yrs.

Singh said that the AAP government will continue to provide free health services, electricity, water and education etc for the next five years after coming to power.

Replying to Singh, Gambhir said that those who cannot afford the services should get it for free. Pointing out Kejriwal, he said that after swearing to remain a Aam Aadmi, he is now enjoying all perquisites - bungalows and cars.

"Those who cannot afford should get the best services free of cost! No doubt about that! But what would you do call a person who swore to remain an 'AAM AADMl' but is now enjoying all perquisites - bungalows, cars and more I guess such hypocrite is called a Jhootliwal!!," he said.

Hitting out at the BJP, Singh said "Several leaders of the BJP have been opposing free basic services such as electricity and water. It is good that they are exposed before the assembly elections," he added.

The AAP Government has been trying to reduce the load from the pockets of the people by providing them free electricity, bus rides to women, health services and education, water and other essential services, he said.
