The political environment of Thailand changed little during the middle '60s. Thanom and his chief deputy Praphas maintained a tight grip on power. The alliance between these two was further cemented by the marriage of Praphas's daughter to Thanom's son Ranong. By the late 1960s, however, more elements in Thai society had become openly critical of the military government which was seen as being increasingly incapable of dealing with the country's problems. It was not only the student activists, but also the business community that had begun to question the leadership of the government as well as its relationship with the United States. Thanom came under increasing pressure to loosen his grip on power when the King commented that it was time for parliament to be restored and a new constitution put into effect. After Sarit had suspended the constitution in 1958, a committee was established to write a new one, but almost ten years later, it had still not been completed. Finally in 1968 the government issued a new constitution and scheduled elections for the following year. The government party founded by the military junta won the election and Thanom remained prime minister.
