Tan Wah Piow

Tan Wah Piow (simplified Chinese: 陈华彪; traditional Chinese: 陳華彪; pinyin: Chén Huábiāo) (born 1948) is a Singaporean-born British lawyer and former student leader who has lived in political exile in London, United Kingdom, since 1976. In 1987, the Singaporean government accused him of being the mastermind behind Operation Spectrum, an alleged Marxist conspiracy to overthrow the government and establish a Marxist state. This operation resulted in the arrest of over two dozen individuals. According to state media, Tan had been influenced by Marxist ideology since the early 1970s. In response to these allegations, the government revoked his citizenship in 1987. He has not returned to Singapore since his departure in 1976.
