David Lammy has said he would seek an arrest warrant for Benjamin Netanyahu if he visited the UK.

The Foreign Secretary said he would be obliged by law to go to the courts seeking permission for the arrest, saying he had no “discretion” over the issue.

The position is a stark contrast to France, which became the latest Western country to say it would not arrest the Israeli prime minister, leaving Britain isolated among its G7 allies.

Last week, the International Criminal Court (ICC), of which Britain is a member, issued an arrest warrant for the Israeli leader, Yoav Gallant, his defence minister, and Mohammed Deif, a Hamas leader.
