He has also been promoted to the rank Leutinent General, by President Maithripala Sirisena.

Senanayake was among the 14 officers who were sent on compulsory retirement by the previous government, after the Presidential election on 2010.
The Army officers were sent on compulsory retirement due to suspicion that they were supporters of former Army Commander Sarath Fonseka.
He was reinstated by President Sirisena in February, 2015.
