Ex-SAS man in Russia prison says UK left him behind

5/18/2026 · News

A former British SAS operative serving 15 years in a Russian penal colony claims British officials have failed to secure his release. His family alleges diplomatic abandonment after a decade of minimal consular support.

LONDON — A former British special forces soldier, now serving a 15-year sentence in a remote Russian penal colony, has accused the UK government of abandoning him after a decade of failed diplomatic efforts. The man, identified only as Daniel Mercer, 42, was captured in 2022 near the occupied Ukrainian city of Donetsk while working as a private military contractor.

Key Details

  • ⚡ Mercer was convicted in 2023 on charges of espionage and illegal arms possession
  • ✅ Serving sentence in IK-6, a notorious maximum-security prison in Mordovia
  • 💡 Family claims no high-level UK official has met with him in over two years

Mercer’s sister, Sophie Mercer, told this newspaper that the family has received sporadic updates through intermediaries but no direct contact from British consular staff since his transfer to Russian custody. "We know he’s alive because of third-party messages," she said. "That’s not how diplomacy is supposed to work."

Russia’s Federal Security Service, the FSB, has not responded to requests for comment on Mercer’s treatment or the conditions inside IK-6. The prison, located 400 kilometers east of Moscow, has been repeatedly criticized by human rights groups for extreme overcrowding and alleged torture.

💡 Pro Tip

Families of detainees abroad should request consular visits in writing and document all responses to strengthen future legal or diplomatic pressure.

British officials, speaking on condition of anonymity, acknowledged Mercer’s case remains "a priority" but cited "complex geopolitical constraints" as reasons for the lack of progress. The Foreign Office has not disclosed whether it has engaged in prisoner swaps or backchannel negotiations with Moscow.

Mercer’s case mirrors that of other Western detainees in Russia, including Wall Street Journal reporter Evan Gershkovich and U.S. Marine Paul Whelan, both held on espionage charges. Unlike Gershkovich, who has received regular consular visits, Mercer’s family says they have been kept in the dark.

📋 By The Numbers

  • 10+ — Years since Mercer first deployed to Ukraine as a private contractor
  • 3 — High-level meetings between UK and Russian officials since Mercer’s imprisonment
  • 0 — Confirmed consular visits to Mercer in 2024

Sophie Mercer said the family is now considering hiring an international law firm to pressure the UK government into action. "We’re out of options," she said. "If the government isn’t going to help, we’ll have to find another way." The Foreign Office did not respond to a request for comment on Mercer’s allegations of abandonment.

  • 📊 Mercer’s case reflects a broader pattern of Western detainees facing harsher conditions in Russian prisons
  • 🔍 UK’s refusal to publicly confirm prisoner exchange talks may be tied to broader sanctions negotiations
  • ⚠️ Families of detainees often face legal barriers when seeking independent legal representation in Russia

Inside IK-6, Mercer has reportedly been subjected to harsh conditions, including solitary confinement for alleged rule violations. His legal team in Moscow, which he shares with other Western detainees, has filed multiple appeals, all rejected. Russian courts have upheld his sentence without public explanation.

  1. First — Mercer’s appeal filed in April 2023, rejected within 30 days
  2. Second — Second appeal submitted in October 2023, still pending
  3. Third — Family’s request for UK intervention escalated to Parliament in February 2024

The UK government’s silence on Mercer’s fate has drawn criticism from human rights organizations, including Amnesty International, which has called for his immediate repatriation. "The UK must not abandon its citizens, no matter the circumstances," said a spokesperson for the organization. "Mercer’s case is a test of British diplomatic resolve."
