As United States government prohibited access to Claude Fable 5 and Claude Mythos 5 to all foreign nationals, including Anthropic’s foreign employees, U.K. Minister for AI and Online Safety Kanishka Narayan stressed on the need to strengthen Sovereign AI structure in Britain.
In a video statement released on late Sunday on X, Labour MP Narayan termed suspension of Anthropic’s Claude Fable and Mythos access by the U.S. government as a threat to British sovereignty, which has not been dealt with the same seriousness.
“I care about sovereign AI because no model is truly neutral . The values built into the one we use every day should be our values. The most pressing, the most significant question for Britain’s national security is the future of our AI”, said Narayan.

“I am not going to pretend there’s a simple switch we can pull. There isn’t. Britain needs more AI capability. This is the central political question of our times and our first duty is to see it clearly before someone else decides for us,” he added.
According to a statement released by Anthropic last Saturday, the U.S. government had asked the AI company to suspend the access of Fable 5 and Mythos for all except U.S. Nationals. The ban includes foreign employees of Anthropic and any other contract based offer to foreign companies even as the organization called it a communication mistake from the White House.
In late April, Anthropic had a very limited release of the Claude Mythos Preview AI model to select research institutes under Project Glasswing with U.K.’s AI Security Institute (AISI) being one of them. AISI, in its evaluation report had remarked that Mythos was the lone AI model to pass their hardest “cyber end-to-end challenge”.
Recently, UK Science Secretary Liz Kendall announced setting up of a £1.1 billion “AI Hardware Plan” to support Britain based firms developing the chips and computing power behind AI. The plan includes £750 million for new national AI supercomputer – including £400 million to purchase next generation AI chips.
“Access to Anthropic’s latest models has been paused for all customers, including in the US and UK. The main lesson: as we debate the future of national security and technological sovereignty, access to AI capabilities is crucial. That’s why this Govt is the first to set up dedicated funding for our AI industry through UK Sovereign AI unit. And just this week, we announced £1.1bn for our AI chip industry,” said Kanishka on X.
