PHUKET: A hundred or more Peoples' Alliance for Democracy supporters from Phuket will join a street march planned by the movement's leaders for Bangkok on Wednesday.

Phuket PAD leader Aparat Chutikam said today that two buses had been organised to travel from Phuket to Bangkok for the walk to Thailand's Parliament.

''Others are expected to make their own arrangements, either driving from Phuket or catching flights from Phuket,'' she said.

The PAD rally at Bangkok's Royal Plaza will oppose the government's move to pass a reconciliation law which the group says is aimed at whitewashing former premier Thaksin Shinawatra and other red shirts.

''We don't agree with this kind of 'harmony','' Khun Aparat, perhaps the most powerful female leader in the PAD, said today. She was keen to make the point that Wednesday's assembly is a rally, not a protest.

''We will walk to Parliament and invite people who think the way we do to go to Parliament to present a letter opposing this legislation,'' she said.

The PAD is the best-known among the yellow shirt support groups. Parliament is expected to consider the bill on Wednesday.

PAD leaders, including Chamlong Srimuang, Pipop Thongchai, Somkiat Pongpaiboon and Panthep Puapongpan, called a media conference yesterday at Lumpini Park in Bangkok to announce the rally.

Yellow-shirt leader Sondhi Limthongkul spoke on "Reforming Thailand and unveiling dirty politics" to thousands of supporters in the park yesterday.

Prime Minister Yingluck Shinawatra is making a four-day visit to Australia but should be back on Wednesday.
