"Our party chief Mamata Banerjee is extremely angry with these incidents (of extortion and involvement in syndicates). We will not tolerate any indiscipline in the party. Strict action will be taken by the party against those who are found to be involved in extortion and syndicate racket," he said.
"Earlier too the party supremo had cautioned a section of leaders and workers against their alleged involvement. On July 21, Banerjee will give clear instructions to party workers against those involved in syndicate racket. Due to a section of leaders the image of our party is taking a toll," the leader said.

Syndicate business in Bengal is run by persons reportedly enjoying political patronage who force promoters and contractors to buy construction materials, often of inferior quality at high prices.
The Opposition had time and again accused a section of TMC leadership for being involved in the syndicate racket. The Left Front too faced similar accusations of patronising syndicates towards the end of its 34-year-long rule.
