Amid a row over irregularities in SSC appointments, West Bengal Chief Minister Mamata Banerjee on Thursday slammed the BJP-led central government for misusing federal agencies for settling political scores.

Banerjee also claimed that there were many discrepancies in government recruitment during the erstwhile Left Front regime in the state, details of which she would reveal soon.

The BJP is running a Tughlaqi' regime (referring to 14th-century Muslim ruler of Delhi Muhammad-bin-Tughlaq) in the country and is trying to divide the nation. They are controlling central agencies and using those to settle political scores," she said, while addressing a public meeting here.

"A lot of things are being said about discrepancies in recruitment. If someone has committed any wrong, then the law will take its own course. But, this vilification campaign should stop. During the Left regime, jobs were given by writing down names on pieces of paper. I will reveal the irregularities soon," she said.

West Bengal minister Partha Chatterjee was on Wednesday evening quizzed for over three hours by the CBI in connection with the irregularities in government school appointments, which has snowballed into a major controversy in the state.

Chatterjee appeared before CBI sleuths in the wake of an order by Calcutta High Court, which termed as "public scam" the irregularities made in the recruitment process.
