Britain and Israel will "work night and day" in preventing Iran from becoming a nuclear power, the foreign ministers of the two countries wrote in a joint article.
"The clock is ticking, which heightens the need for close cooperation with our partners and friends to thwart Tehran's ambitions," Yair Lapid and his UK counterpart Liz Truss wrote in the Telegraph newspaper on Sunday.
Prime Minister Naftali Bennett said earlier in the day that his country was "very worried" that world powers will remove sanctions on Iran in exchange for insufficient caps on its nuclear program, as negotiators convene in Vienna on Monday in a last-ditch effort to salvage a nuclear deal.
Meanwhile, Israel and Britain will sign a 10-year agreement on Monday to work closely on areas such as cybersecurity, technology, trade and defense, according to the Telegraph.
The foreign ministers added in the article that Israel will officially become Britain's "tier one" cyber partner, in a bid to improve its cyber defenses as countries around the world face increased threats.
"Israel and the UK are the closest of friends, and today we are deepening that partnership to become even closer," Lapid and Truss wrote. "Together, we will forge ahead and ensure the future is defined by liberal democracies who believe in freedom and fairness."
Lapid is currently in London on a two-day trip which was slimmed down due to the new COVID-19 Omicron variant.
"The minister's visit will focus on the resumption of nuclear talks in Vienna as well as the deepening of bilateral relations between Israel and Britain and France," the Foreign Ministry said in a statement, according to Times of Israel.
