Its Chief, Datuk Jumat Idris, said his Beaufort counterpart should be a "gentleman" and state his stand now whether he is still with the Barisan Nasional (BN) or not.
"If he is still with BN, then he should say so...if not, then he should in a gentleman manner resign from Umno and BN as well as relinquish his Deputy Minister post.
"Don't hide until the last minute when the Parliament is dissolved to jump to the other side," said Jumat when asked to comment on the issues widely spread in the Internet about Lajim's speech in the open house hosted by a Parti Keadilan Rakyat (PKR) Sabah leader, Datuk John Ghani, last month.
Jumat said in the first place, Lajim had breached the party's constitution by attending an opposition gathering.
It was also mentioned that among those who attended the gathering was Pakatan's MP Datuk Nizar Jamaluddin.
Lajim, however, had said that his speech at the function had been exploited and that he was there as he was invited.
