Thiruvananthapuram: CPM MLA O R Kelu was sworn in as minister in the CPM-led LDF government on Sunday. 

The oath-taking ceremony, which took place at the Raj Bhavan, was attended by Chief Minister Pinarayi Vijayan. 

Earlier, the Chief Minister's Office (CMO) had sought the convenience of Governor Arif Mohammed Khan for the swearing-in ceremony of Kelu on Sunday afternoon.

The 54-year-old CPM leader from a tribal community in Wayanad will replace K Radhakrishnan, who resigned as Minister for Scheduled Castes and Scheduled Tribes, Parliamentary Affairs and Devaswom after being elected to the Lok Sabha from the Alathur seat.

Kelu was recommended by the CPM state committee to be inducted as a minister in the LDF cabinet.

Although there is a clear indication that Kelu will get the portfolio of Scheduled Castes and Scheduled Tribes (SC/ST), sources said there will be a minor shuffle in the portfolios previously held by Radhakrishnan.
