He took his oaths before Speaker Mahinda Yapa Abeywardena soon after the parliamentary proceedings commenced.
Last week, the Election Commission had named Kugathasan to fill the parliamentary seat that became vacant following the passing of former Tamil National Alliance (TNA) leader Rajavarothiam Sampanthan.
Former TNA leader and former Opposition Leader R. Sampanthan passed away on July 01 at the age of 91 while receiving treatment at a private hospital in Colombo.
Sampanthan was the incumbent MP for Trincomalee District and had served in five parliaments since 1977.
