Leigh Day has brought cases against the German and Japanese governments for their mistreatment of prisoners of war (PoWs) and labourers during the second world war.
In the 1990s, Leigh Day represented thousands of former British prisoners of war detained in Japanese camps in a claim in a legal action against the Japanese Government in the Tokyo District Court. In November 2000, the British Government agreed to make ex gratia payments of £10,000 to each surviving Briton held prisoner by the Japanese during the Second World War. Over twenty thousand former prisoners of war and internees received compensation.
In the 1999, Leigh Day was also asked by the Federation of Poles in Great Britain to work with them to bring a claim against the German Government on behalf of former slave labourers in Nazi Germany. Proceedings were also issued in the US against German firms. Leigh Day subsequently entered into negotiations with the German and Polish Governments and went on to resolve the claims brought by those enslaved by the Germans during the Second World War.
