British Prime Minister Boris Johnson said this week that Israeli plans to annex parts of the West Bank would “amount to a breach of international law.”

Johnson was questioned on the issue in the House of Commons by fellow Conservative Party member Crispin Blunt, who asked about about possible sanctions if Israel goes ahead with plans to annex settlements in the West Bank.

“I believe that what is proposed by Israel would amount to a breach of international law. We have strongly objected. We believe profoundly in a two-state solution and we will continue to make that case,” Johnson replied to Crispin, who the British newspaper the Jewish Chronicle describes as a “long-term critic of Israel.”

Prime Minister Benjamin Netanyahu has set July 1 as his deadline for beginning to assert Israeli sovereignty over settlements on land Israel gained in the 1967 Six Day War.
