The British Foreign Secretary, David Miliband, contacted Livni and his Israeli counterpart Avigdor Lieberman to formally explain the incident and apologize on behalf of the British government. Miliband had expressed concern at the situation and said officials were looking "urgently at ways in which the UK system might be changed in order to avoid this sort of situation arising again". Judges in the United Kingdom can issue arrest warrants for war crimes suspects around the world under the Geneva Convention Act 1957 without any requirement to consult public prosecutors, which was something Miliband described as "unusual". J Street applauded Miliband's rejection of the warrant and "his promise to pursue a change in the law that would prevent unfortunate events like these from happening in the future." Prime Minister Gordon Brown expressed his regret over the warrant and spoke to Livni, reassuring her that she was "most welcome in Britain any time." Livni's office later stated that Brown promised to seek legislative changes to ensure no Israeli official would risk arrest while on British soil.
