Littlewood (1965)

By 1963, the number of animals involved in experiments was counted in millions while the Cruelty to Animals Act (1876) had remained largely unchanged [55]. A Departmental Committee on Experiments on Animals, chaired by Sir Sidney Littlewood was assigned "to consider the present control over experiments on living animals, and to consider whether, and if so what, changes are desirable in the law." Published in 1965, the Littlewood Report finally established an uncompromising recognition that, "the use of muscle relaxing drugs which, in e ffect, renders an animal physically helpless whilst leaving it fully conscious, opens the way to experiments of extreme cruelty."
