British Prime Minister Keir Starmer is being urged by senior members of his government to reassess his policy toward China and take a tougher stance on the risks it poses to U.K. national security in the wake of a collapsed espionage case.

Several Cabinet ministers are concerned that Starmer has taken too generous an approach to Beijing and want him to commit clearly to prioritizing national security over any economic benefit from the relationship, according to people familiar with their thinking.

At least two Cabinet members also want the premier to decline permission for China to build a new mega-embassy near the City of London on security grounds, the people said. They spoke on condition of anonymity discussing internal deliberations over government policy.
