Various Marxist–Leninist groups endorsed Pol Pot's government while it was in power. The small Canadian Communist League (Marxist–Leninist), for instance, praised his government and sent a delegation to meet with him in Phnom Penh in December 1978. Another sympathiser who visited Pol Pot that year was the Scottish communist Malcolm Caldwell, an economic historian based at London's School of Oriental and African Studies. He met with Pol Pot, but was murdered shortly afterward; the culprit was never identified. Also in 1978, the Khmer Rouge met with delegates of the Swedish Cambodian Friendship Association, whose members openly sympathised with Pol Pot's regime. One of its members, Gunnar Bergström, later noted that in the 1970s he had been a Marxist–Leninist who had become dissatisfied with the Soviet Union and believed that the Cambodian government was building a society based on freedom and equality. In his view, the Khmer Rouge regime was "an example to the Third World". Bergström noted that he and his fellow members had heard about atrocities that were taking place but "did not want to believe them".
