Prime Minister Datuk Seri Najib Tun Razak is confident that Datuk Amar Jamilah Anu from Barisan Nasional, who won the Tanjong Datu by-election today, will bring in more progress and continous development to the constituency.

Commenting on her landslide victory, he said Jamilah was now the best person to continue the legacy left by her late husband Tan Sri Adenan Satem, who was the incumbent and Sarawak's fifth chief minister.

"Congratulations to BN candidate Puan Sri Jamilah Anu who was elected by the Tanjong Datu voters to be their assemblyman. Long live Barisan!" Najib said via his Facebook and Twitter accounts tonight.

Jamilah defeated two candidates, namely Johnny Aput from the Sarawak Reform Party (STAR) and Rapelson Richard Hamit of Parti Bansa Dayak Sarawak (PBDS) Baru in the by-election.
