LONDON: Britain’s former minister for veterans has “provided further information” to a public inquiry into claims of war crimes by special forces in Afghanistan, a spokeswoman said Thursday, after he was threatened with jail.

Johnny Mercer has said that “multiple officers” told him about alleged murders and a subsequent cover-up during the Afghan conflict, but he refused to divulge their identities.

The Independent Inquiry Relating to Afghanistan, which is examining the claims, gave him until 4:00 pm (1500 GMT) on Thursday to provide the names, insisting the information would be in confidence.

The judge-led inquiry had previously issued Mercer with an order under Britain’s Inquiries Act 2005 warning him he could be fined, imprisoned or both if he did not comply.

“Mr Mercer has provided further information in response to the Section 21 notice and agreed to assist the inquiry further,” an inquiry spokeswoman said.

“The inquiry team will be taking this forward. For the time being, the chair will not be taking further action in relation to the Section 21 notice or making further comment.”

Mercer, a former British Army officer who served three tours of Afghanistan, repeatedly refused to disclose the names when he gave evidence at the inquiry in February.

The inquiry is examining claims that between 2010 and 2013 a British special forces unit executed Afghan males of “fighting age” who posed no threat.

The former minister, who lost his seat at this month’s general election, said in response to the latest development: “My position remains unchanged from the beginning of the year.”

“I will always do all I can to assist this important inquiry. I will not betray those I served who have confided in me, whatever the cost,” he wrote on social media.
