Jailed AAP leader Sanjay Singh was not sworn-in as Rajya Sabha MP on Monday as Rajya Sabha Chairman Jagdeep Dhankhar refused to allow the former Delhi minister to take the oath, ANI reported.
Dhankhar said the matter was currently with the Privileges Committee.
Sanjay Singh, arrested in a money laundering case linked to the now-scrapped Delhi excise policy, was renominated by the AAP for another term in Rajya Sabha in January.
Besides Singh, the AAP nominated former Delhi Commission for Women (DCW) chief Swati Maliwal, and chartered accountant Narain Das Gupta to the Rajya Sabha.
Last week, a Delhi court allowed Sanjay Singh to go to Parliament under police custody and take oath as a Rajya Sabha MP on February 5.
Special judge MK Nagpal had directed the jail authorities to take Sanjay Singh to Parliament at 10 am to take the oath.
The senior AAP leader was arrested by the Enforcement Directorate (ED) last year.
