After the war he returned to journalism in Durban with the Argus Newspaper group and would eventually become an assistant editor. In October 1957, he was offered the role of editor of the
Rand Daily Mail, one of many English South African newspapers owned by Anglo American.During June and July 1965, he and journalist
Benjamin Pogrund wrote a series of articles on conditions in South African prisons for black South Africans in
Port Elizabeth,
Pretoria and the Cinderella Prison in
Boksburg based on interviews with prison officials and prisoners. The articles cited assaults on prisoners, sodomy and unhygienic conditions in these prisons. During this period the newspaper was subjected to around the clock surveillance, Security Branch raids, the eavesdropping of the editor, journalists and the newsroom as well as infiltration by police informants and the intimidations and prosecution of informants. The attacks against the newspaper were also taken up by the government controlled
South African Broadcasting Corporation (SABC) and the Afrikaner newspapers and silence from the English newspapers. The government would instead of investigating the claims through the means of a judicial inquiry, prosecute two prisoners and two wardens sentencing one to three years in jail, 'confessing' to making up the charges and being a paid informant of the paper, a claim that the Rand Daily Mail was not allowed to challenge at his trial. They would be charged with contravening South Africa's Prisons Act and would eventually appear in court in November 1968, before Justice
P. M. Cillié, in a trial that last 88 days. The prosecution would successfully argue that 17 allegations in the articles were false and the judge agreed finding the two guilty on two charges of publishing false allegations and not 'verifying' the facts. Gandar was fined R100 on both charges or three months imprisonment and Pogrund received two three-month sentences suspended for three years and subject to him not contravening the Prison Act. In 1965 he was fired as editor of the Rand Daily Mail by it board of directors because of poor circulation figures but after a threatened walk-out by the senior journalists, Gandar was appointed as editor-in-chief and
Raymond Louw appointed as the new editor. Gander would remain in his new role until 1969. Gandar was appointed the first director of the
Minority Rights Group in Britain which investigated and publicized the treatment of the worlds minorities, a position that lasted three years and afterwards returned to South Africa. ==Honours==
