Senior CPM leader E P Jayarajan rejoined the Pinarayi Vijayan cabinet after he was sworn in on Tuesday.
Governor P Sathasivam administered the oaths of office and secrecy to Jayarajan at a brief ceremony at the Raj Bhavan.
The Opposition boycotted the ceremony. Jayarajan is back to the cabinet after 22 months following his resignation as minister due to nepotism charges.
He was forced to quit Pinarayi Cabinet in October 2016 after the appointment of his nephew P K Sudheer Nambiar, son of P K Sreemathi MP, as MD of Kerala Industrial Enterprises Ltd kicked up a storm. An embarrassed LDF government later quashed the appointment.
He is the second minister to return to the LDF ministry after being forced to step down. NCP’s A K Saseendran had resigned as Transport Minister in March 2017 over a phone conversation controversy, but he returned to the ministry in February this year after his replacement.
