A sharp diplomatic standoff between Israel and the United Kingdom has intensified in recent days, as top Israeli officials have issued explicit warnings that any new British sanctions targeting illegal Israeli settlements in the occupied West Bank will trigger a swift and proportional retaliation from Jerusalem.
The public escalation began during an interview with Israeli domestic news outlet Ynet this Tuesday, when Israeli Foreign Minister Gideon Sa’ar laid out Israel’s position amid growing tensions over Israel’s recently announced plan to expand settlement construction in the West Bank’s highly contentious Area E1. Sa’ar levelled criticism directly at the UK’s current Labour government, accusing the administration of pursuing a coordinated agenda against Israel. He noted the government has already restricted Israeli defense imports and imposed punitive measures on senior Israeli ministers, actions that set the stage for the current crisis.
The Labour government first imposed targeted sanctions in June 2025, when it blacklisted far-right Israeli cabinet members Itamar Ben Gvir and Bezalel Smotrich for their role in inciting settler violence against Palestinian communities during Israel’s ongoing military campaign in Gaza. This Tuesday, UK Foreign Secretary Ed Miliband formalized plans for further action during an address to British Members of Parliament, confirming his government would roll out a “comprehensive” package of sanctions in the coming weeks.
Miliband emphasized that Israel’s proposed E1 development – which would connect Jerusalem to the existing Ma’ale Adumim settlement and other Israeli built communities east of Jerusalem, effectively splitting the core territory Palestinians have earmarked for their future independent state – poses an existential threat to the prospect of a two-state solution to the Israeli-Palestinian conflict. “This government will not acquiesce in the destruction of the two-state solution,” Miliband told lawmakers, confirming that concrete measures would be outlined in the near term.
The proposed E1 project has been a flashpoint for international criticism for decades, as its implementation would permanently cut off the geographic contiguity of the West Bank, making a sovereign, viable Palestinian state functionally impossible. Sa’ar rejected Miliband’s announcement outright, framing the planned sanctions as an unjust attack on Israeli interests. “If Britain acts against Israel, Israel will act against Britain,” Sa’ar told Ynet. “They will be making a big mistake. Israel will not be a passive victim of this policy, and we will defend our rights, our interests and our people.” Sa’ar added that Israeli authorities are already making preparations for potential sanctions and finalizing their retaliatory response.
This public exchange is the latest high-profile clash between the two countries’ top diplomats: just last month, Sa’ar and Miliband traded critical remarks over the E1 settlement expansion plan, opening the rift that has now widened into a full diplomatic crisis.
According to a Monday report from Israeli right-wing newspaper Ma’ariv, Israeli officials have already privately warned London that any new sanctions on settlements will be met with a “substantial” response. The report noted that Israeli leadership has not yet finalized the form of retaliation, with multiple options on the table including diplomatic and economic measures. One option reportedly under active consideration is the expulsion of British representatives from the US-led International Gaza Support Centre (IGSC), the multinational body established to monitor the ongoing Israel-Hamas ceasefire in Gaza.
This would not be an unprecedented step for Jerusalem: just last week, Israel expelled Dutch officials from the IGSC in response to the Netherlands’ recent ban on imports of goods produced in illegal Israeli settlements. Earlier this year, Israel similarly removed Spanish representatives from the body, accusing the Spanish government of “obsessive anti-Israel bias.”
Still, Ma’ariv reported that Israeli leadership is weighing the potential long-term risks of a harsh retaliation against the UK, noting that future British governments led by the Conservative Party or a Reform UK-aligned administration are widely expected to adopt a far more pro-Israel stance. The report also confirmed that the United States administration has been working behind the scenes as an intermediary between the two governments, actively pressuring London to abandon its planned sanctions package.
