Sabah PKR rep Dr Roland Chia has said he will make a formal announcement on his position after Christmas.

"To media and friends. Thanks for your concern. I am currently abroad. Will make formal media statement after Christmas," he stated in a Twitter post.

Yesterday, PKR secretary-general Rafizi Ramli said the Inamam assemblyperson has informed the party of his intention to vacate the seat due to health reasons.

He said Chia, who is a dentist, had also written to inform that his medical condition was "serious".

On Wednesday, Chia wrote on Twitter and Facebook that he would quit as the assemblyperson for Inanam due to health reasons.

However, he had yet to communicate the matter formally with his party or the Sabah PKR chapter.

The 44-year-old politician is a first time assemblyperson. His resignation would pave the way for a by-election in the state.
