A member of the council continually from 1991, she polled the highest percentage, 65 pc, of votes in the party at the recent local government polls.
However, the UNP leadership is planning to re-appoint Sunethra Ranasinghe as the mayor.
Of the 19 UNP members of the council, Ranasinghe is opposed by six.
The matter has aggravated, with Ruwan Liyanagunawardena and Ananda Fernando too, expecting the top position.
The SLPP has 19 members in the Dehiwela-Mt. Lavinia MC as well, followed by six for the UPFA and four for the JVP.
In the meantime, Basil Rajapaksa is campaigning to obtain the mayor position to SLPP’s Keerthi Udawatte, for one year duration, after the party’s mayoral candidate Dhanasiri Amaratunga lost his electoral division.
He failed to get elected to the MC, also due to the mandatory women’s representation.
