Residence of Pracharaj leader Sanoh Thienthong was quiet Saturday morning, several hours before his son was going to get married.
No politicians have so far visited him on this special occasion. But they are expected to join the wedding to be held at Impact Muang Thong.
The wedding can open opportunities for Mr Sanoh to lobby MPs to back Puea Pandin leader Pracha Promnok as new prime minister.
Mr Sanoh supports Pol Gen Pracha as the leader of the new government. Pol Gen Pracha also received backing from ousted premier Thaksin Shinawatra.
