Now it is Ampang MP Zuraida Kamaruddin (pic) who has been denied entry into Sarawak, making her the fourth PKR leader from the peninsula to be barred from the state in as many days.
The PKR Wanita chief, who arrived in Sibu at 2.30pm on an AirAsia flight, was, like three of her party colleagues before her, told on arrival by immigration officers that she was barred from entering the state.
She will be put on the next flight back to Kuala Lumpur.
PKR leaders are now wondering if Selangor Menteri Besar Tan Sri Khalid Ibrahim, who will be flying in later this evening, would also be denied entry into Sarawak.
On Tuesday, immigration officers had stopped PKR strategic director Rafizi Ramli, member of Parliament Tian Chua and their secretary-general Datuk Saifuddin Nasution Ismail at Sibu airport and told them they were not allowed to enter the state.
Rafizi and Chua, who flew to Sarawak together with PKR de facto leader Datuk Seri Anwar Ibrahim, were told by immigration officers that their names were in the list of people barred from entering the state.
Anwar, however, was allowed in.
Earlier on Tuesday morning, Saifuddin was stopped at the Sibu airport and informed he was barred from entering the state.
All three were put on the next flight back to Kuala Lumpur.
PKR has reacted angrily to the barring of its national leaders from the by-election with its Sarawak deputy chairman See Chee How saying it was an abusive and misuse of the government's power on the immigration autonomy.
In a text message, See said he was disappointed with Sarawak Chief Minister Tan Sri Adenan Satem whom he accused as going back on his words not to bar opposition politicians from the state.
Political analyst Dr Mohd Faisal Syam Abdol Hazis has suggested that the “sums game”, or the need to win by a big a majority, is why Adenan barred the PKR national leaders from entering the state to campaign for the by-election as they could make a difference to the result.
“There's no valid reason to bar the PKR leaders unless Adenan and the state Barisan Nasional (BN) believe they could take the shine off a BN victory.
“This is a safe seat. For the new chief minister, I believe he wants to put his stamp on Sarawak politics in the best possible way.
"Win by as big a majority as possible. Stamping that mark starts in Balingian,” Faisal said. – March 27, 2014.
