Political positions Mallaghan called for the British government to conduct an inquiry into the murder of Sean Brown. He supported the results of an inquiry that determined that the special Air Service was not justified in killing four people at the Clonoe ambush.

During the 2024 election Mallaghan agreed to the six demands of the Palestine Solidarity Campaign which consisted of a ceasefire in the Gaza war, restoring funding to UNRWA, an embargo of weapon sales to Israel, support for the International Court of Justice and International Criminal Court, ending trade agreements with Israel, and protecting Boycott, Divestment and Sanctions. In 2025, he called for the United Kingdom to stop providing weapons to Israel and criticised Israel's treatment of Palestinians and its actions during the Gaza war.
