The Sarawak United People's Party (SUPP) will "take the bull by the horns" in rectifying its shortcomings following its  defeat in the recent Sibu parliamentary seat by-election, said its president Dr George Chan.

He said the need for SUPP to effectively communicate with the grassroots was conveyed by Prime Minister Najib Abdul Razak, who chaired the Barisan Nasional (BN) supreme council meeting in Kuala Lumpur, last night.
