New Delhi: Congress president Rahul Gandhi has written a letter to Bengal chief minister Mamata Banerjee as he extended his support to her ‘united India rally’ in Kolkata on Saturday.

Gandhi sent his party’s support to the Trinamool Congress (TMC) in hopes that it would send a message of “united India together”.

"The entire opposition is united in our belief that true nationalism and development can only be defended on the tested pillars of democracy, social justice and secularism, ideas that the BJP and Mr Modi are intent on destroying," Gandhi wrote.

He said that there are ‘powerful forces’ in India that are “fanned by anger and disappointment of hundreds of millions of Indians who had seen through false promises and lies peddled by the Modi government."

The Congress chief added that these ‘forces’ were moved by an idea of India in which the voice of "every man, woman and child would be heard", no matter what their religion, economic status or region.

"I extend my support to Mamata Di on this show of unity and hope that we send a powerful message of a united India together," Gandhi wrote in his message.

However, Rahul and UPA chairperson Sonia Gandhi will not be attending the event in Bengal. Mallikarjun Kharge and Abhishek Manu Singhvi will be representing the Congress at the event.
