Signal threatens to withdraw from UK over encryption backdoor proposals
Meredith Whittaker says Signal would 'absolutely, 100% walk' from the UK rather than compromise its end-to-end encryption.
Signal’s president Meredith Whittaker has drawn a hard line in the sand. The encrypted messaging app will leave the UK entirely before it weakens its encryption protocols to satisfy government regulators.
Whittaker’s warning isn’t new, but it’s getting louder. On June 8, 2026, the Signal Foundation published a statement titled “Surveillance Is Not Safety,” taking direct aim at UK proposals that would require phone screening and content scanning capabilities, measures that privacy advocates argue would functionally destroy end-to-end encryption.
What the UK wants, and why Signal won’t comply
The roots of this standoff trace back to the UK’s Online Safety Act, which received royal assent in October 2023. The law grants Ofcom, the UK’s communications regulator, the authority to impose measures against illegal content on messaging platforms. In practice, it creates a framework where regulators can demand that platforms scan encrypted messages for prohibited material.
Whittaker has been unambiguous about where Signal stands. She stated that Signal would “absolutely, 100% walk” from the UK rather than weaken its encryption protocols. Signal is a nonprofit. It doesn’t have shareholders demanding UK market retention at any cost.
The latest UK proposals reportedly include requirements for phone-level screening and content scanning. Signal’s June 8 statement framed these as the “latest threat to privacy,” positioning the regulatory push as part of a broader global trend rather than an isolated British policy experiment.
A pattern of pushback across borders
The UK isn’t the only government testing Signal’s resolve. In 2025, Sweden proposed its own encryption-weakening legislation, prompting a similar reaction from the messaging platform. Signal has consistently opposed government-mandated backdoors or scanning mechanisms anywhere in the world, regardless of the stated justification.
As of June 10, 2026, details about the UK government proposals remain sparse, signifying a period of uncertainty in regulatory frameworks around digital privacy and user data safety.
