He worked for two years as a school teacher in London and ran several youth organisations in South London. In 1971 he published a pamphlet How the West Indian Child Is Made Educationally Subnormal in the British School System: The Scandal of the Black Child in Schools in Britain. The pamphlet explained that British schools had a pervasive bias toward treating white children as normal, which led to black children being labelled as "educationally subnormal". Coard wrote:
The children are therefore made neurotic about their race and culture. Some become behaviour problems as a result. They become resentful and bitter at being told their language is second-rate, and their history and culture is non-existent; that they hardly exist at all, except by the grace of whites.
In 1976 Coard returned to Grenada, soon becoming active in Grenadian politics. Soon after returning home, he joined the New Jewel Movement, his childhood friend's left-wing organisation. Ran for and won a parliamentary seat in St. George's in the 1976 elections. The NJM, led by Maurice Bishop, successfully led a bloodless coup against Eric Gairy's government on 13 March 1979. The radio station, military barracks and police stations were targeted. Before long, they had control of the entire island. The NJM then announced the temporary suspension of the constitution and parliamentary rule. Influenced by Marxists such as Daniel Ortega and Fidel Castro, Bishop's NJM established a revolutionary government in Grenada. Aid from Cuba allowed the NJM to build Point Salines International Airport, an international airport with a runway in St. George's. In 1980, Coard was the head of a delegation to Moscow to formalise relations with the Soviet Union.
The removal of Bishop
Bernard Coard was serving as the revolutionary government's Minister of Finance, Trade and Industry, as well as the Deputy Prime Minister under Bishop. It is alleged that Coard ordered Bishop put under house arrest on 19 October 1983 and took control of the government. As word of Bishop's arrest spread, large demonstrations broke out in many places. A demonstration in the capital led to Bishop being freed from house arrest by the demonstrators. Bishop and seven others including cabinet ministers of the government were killed under unresolved circumstances. Just after Marines landed in Grenada, Coard, along with his wife Phyllis, Selwyn Strachan, John Ventour, Liam James, and Keith Roberts were arrested.
Trial and prison
They were tried in August 1986 on charges of ordering the murder of Maurice Bishop and seven others. Bernard Coard was sentenced to death, but this was commuted to life imprisonment in 1991. He served his sentence in Richmond Hill Prison, where he was engaged in teaching and instructing fellow inmates in many subjects, including economics and sociology. In September 2004, the prison in which he was held was damaged by Hurricane Ivan and many inmates took the opportunity to flee, but Coard said he chose not to escape, saying he would not leave until his name was cleared.
Release
On 7 February 2007, the London-based Privy Council ordered a re-sentencing of Coard and the others convicted for the 1983 killing of Bishop and some of his cabinet colleagues. The re-sentencing hearing began on 18 June. On 27 June, the judge gave Coard and his fellow defendants a 30-year sentence, which included the time already spent in prison. On 5 September 2009, Coard was released from prison. Upon release he said he did not want to be involved in politics again. Bernard Coard has three children: Sola Coard, Abiola Coard, and Neto Coard.
