DATA divulged as part of the Afghan leak could be used by “states who want to do us harm,” the chairman of Parliament’s intelligence and security committee said today.

Speaking to BBC Radio Scotland, Lord Beamish lamented that no-one “saw fit” to tell the committee about the leak and the subsequent superinjunction which blocked it being reported.

The details of more than 100 Britons, including those working as spies and in special forces, were included in the massive data breach that resulted in thousands of Afghans being secretly relocated to Britain.

Defence sources have said information relating to personnel was included in the spreadsheet after they had endorsed the applications of Afghans who requested to be brought to the country.

Lord Beamish told BBC Radio Scotland: “I think there are serious constitutional issues here.”

He said the most concerning element of the breach was that “other states who want to do us harm” could use it not just to target individuals, but “as a way of seeing other operations” being carried out by the security services.

Defence Secretary John Healey has also been accused by the Liberal Democrats of misleading Parliament over the Afghan data leak.

According to Hansard, Mr Healey told the Commons on Tuesday: “To the best of my knowledge and belief, no serving member of our armed forces is put at risk by the data loss.”

Lib Dem leader Sir Ed Davey said: “Today we found out that appears to be false.

“We need to know if any serving members of the armed forces were impacted.

“And the Defence Secretary must urgently come before Parliament to answer the question of whether he knowingly misled MPs and the public.”

Downing Street defended Mr Healey and said his Commons statement was “accurate.”
