Former shadow chancellor John McDonnell has suggested that the Israeli ambassador to the UK should face expulsion amid efforts to end alleged war crimes in Gaza. McDonnell called for Israel's isolation 'economically and militarily' and said that UK authorities could play a 'leading role' in that process. Several MPs called for sanctions in the Commons on Tuesday, as Foreign Office minister Hamish Falconer took questions about the humanitarian crisis in northern Gaza. The minister vowed to make 'disagreement clear through all channels', but did not comment on whether the Israeli ambassador would face expulsion.
