In a move that may trigger further tussle between the Centre and the Aam Aadmi Party dispensation, the Delhi Bharatiya Janata Party has registered a complaint with the Anti-Corruption Branch, accusing the Kejriwal government of indulging in corruption in contract of High Security Number Plates, a charge denied by it.

Two senior BJP leaders including national secretary R P Singh and Harish Khurana recently complained to the ACB regarding the alleged 'scam' in the HSNP project.

The complaint claimed a contract between Delhi government's Transport Department and a private company was 'terminated' after which the company went into arbitration but it was allowed to issue the number plates 'under the garb of arbitration'.

"The two committees formed by Delhi government in 2014 and 2015 had found various irregularities such as procurement of the plates from unapproved source and overcharging but the company was allowed to issue the registration plates under the garb of arbitration," Khurana alleged.

Rubbishing allegations of irregularities, the AAP government said in January 2014, the then Transport Minister Sourabh Bhardwaj had formed a three-member fact-finding committee.

On the basis of the committee's report, the AAP government had terminated the contract with the company in February 2014, said a senior government official.

Singh alleged in his complaint that the scam was to the tune of Rs 300 crore.
