Gordon Brown, the British prime minister, has phoned Tzipi Livni, Israel's former foreign minister, to tell her she is still welcome in Britain, despite a warrant that was issued in London for her arrest. In a telephone call on Wednesday, Brown also reiterated his determination to change the law that allows British courts to issue warrants for alleged war crimes suspects around the world, Livni's office said. The arrest warrant was issued over Livni's role during Israel's war on Gaza, but was later withdrawn after she cancelled her visit to London. The gesture did little to calm the uproar in Israel over the arrest attempt, the latest in a string of Israeli leaders to be threatened with legal action in Britain.
