Sisavang Vong
Nationalist leader Son Ngoc Thanh, who had been exiled in Japan and was considered a more trustworthy ally than Sihanouk, returned to Cambodia and became Minister of foreign affairs in May and then Prime Minister in August. In Laos however, King Sisavang Vong of Luang Phrabang, who favoured French rule, refused to declare independence, finding himself at odds with his Prime Minister, Prince Phetsarath Rattanavongsa, but eventually acceded on 8 April.
