The 1Malaysia concept introduced by Prime Minister Najib Abdul Razak will be put to the test in Sabah for the first time, when the people of Batu Sapi cast their votes in the parliamentary seat by-election.

Already two opposition parties, Sabah Progressive Party (SAPP) and PKR, have indicated their intention to take part in the Nov 4 by-election or more or less have decided on their candidates by now to challenge the ruling BN's candidate from Parti Bersatu Sabah (PBS).
