Keir Starmer has previously argued Serbia waged genocide against Croatia
A 2014 video of Keir Starmer arguing that Serbia committed genocide against Croatia has resurfaced, prompting further scrutiny of the British prime minister's denial that Israel is committing the same crime in Gaza.
Last week, Starmer was asked in parliament to share his definition of genocide and to outline what action he was taking to save the lives of people in Gaza.
In response, he said he was "well aware of the definition of genocide" and that this explains why he has "never described or referred to [the situation in Gaza] as genocide".
His remarks followed similar denials from Foreign Secretary David Lammy, who suggested that Israel is not committing genocide in Gaza because millions of people have not been killed.
As a human rights lawyer, Starmer was part of the legal team representing Croatia before the International Court of Justice, in a case where both Serbia and Croatia accused each other of violating the 1948 Genocide Convention
