LONDON: The UK’s attorney general will not agree to ban the sale of weapons to Israel unless it can be proved they will be used to break international law. Richard Hermer, the government’s most senior legal adviser, intervened after Foreign Secretary David Lammy announced a review into the granting of licenses to export weapons amid fears they could be used in Gaza. Lammy suggested that “offensive” weapons would not be sold to Israel, but left room for the export of “defensive” equipment, criteria which have proved difficult for Foreign Office officials to establish.
