About 50,000 red shirts from the Northeast will meet former prime minister Thaksin Shinawatra in Vientiane during the Songkran festival next month.
Red shirt leader Nisit Sinthuphrai said about 50,000 Thaksin supporters are expected to leave for Laos to meet him there as he pays a brief visit to Laos and Cambodia during the festival.
The red shirts would gather at the stadium of the Nong Khai provincial administrative organisation on April 11 and leave for Vientiane the next morning.
Their travels will be broadcast live on the pro-Thaksin Asia Update television station.
Mr Nisit said red shirt co-leader Jatuporn Prompan would make arrangements for another group of red shirts to meet Thaksin in Siem Reap of Cambodia.
Theppanom Namlee, a red shirt leader in Surin province, said red shirts from Yasothon, Buri Ram, Roi Et and Surin provinces would pass the Chong Jom border pass in Kap Choeng district of Surin on April 13 and head for Thaksin's whereabouts.
Mr Theppanom said some 10,000 red shirts are expected to join the trip to meet Thaksin who will be in Siem Reap on April 14 and 15.
Mr Theppanom said MPs of the Pheu Thai Party should travel along.
Thaksin made a phone call to a meeting of his northeastern red shirt supporters last Saturday.
Thaksin, who has been living in Dubai in self-imposed exile since 2008, invited his supporters to meet him either in Siem Reap or in Vientiane during the Songkran festival. He will be in Vientiane on April 12 and 13.
Kwanchai Praipana, the red shirt's leader in Udon Thani province, said he would lead about 1,000 red shirt followers from Udon Thani to meet Thaksin at Phetchampa Hotel in Vientiane on April 12.
Red shirts plan to organise a ceremony to pray for Thaksin's well-being and smooth return to Thailand.
Thaksin's supporters from Udon Thani will return to their home province on the same day.
Mr Kwanchai said he would organise an event on April 7 at which red shirts would launch a drug campaign with police.
He expects Thaksin to phone in to greet his supporters on that day.
