Mamata wishes Cong workers on foundation day

"Greetings and warm wishes to all at @INCIndia on their 132nd Foundation Day," Banerjee tweeted.

Banerjee's tweet comes a day after she along with Congress leader Rahul Gandhi and regional parties sought to put up a united face against demonetisation by demanding the resignation of Prime Minister Narendra Modi.

After the meeting of 8 parties and their joint press conference against demonetisation in New Delhi yesterday, Banerjee vowed to rope in more parties and take on the government in a united manner.

The newfound thaw in ties comes after the Congress and CPI(M) had struck up an alliance in the last West Bengal assembly polls, which Banerjee had termed as "unethical and immoral".

Banerjee came to politics through her stint in Congress, first as a Youth Congress leader and then as an MP. She had floated her party Trinamool Congress in 1998 in the wake of sharp differences with Congress.
