LONDON (AP) 鈥� The British government said Thursday it will keep the country鈥檚 spies on a tighter rein after a report found misled courts about its ties to a neo-Nazi informer accused of attacking his partner.
Home Secretary Shabana Mahmood said she is taking 鈥渦rgent action鈥� to strengthen oversight of the U.K.鈥檚 domestic security service after a tribunal found it repeatedly gave 鈥渁 false account鈥� of what had happened.
MI5 apologized and paid compensation earlier this year to settle a legal claim brought by a woman over her treatment by an allegedly abusive ex-partner. The man was an MI5 informant, identified in court as Agent X.
MI5 maintained in sworn testimony that it had neither confirmed nor denied that Agent X was an agency informant spying on extreme-right groups. But in fact an MI5 officer had disclosed the information during a conversation with a BBC journalist who was investigating Agent X.
The Investigatory Powers Tribunal, which investigates allegations against Britain鈥檚 intelligence services, said MI5 had misled three courts because a false narrative was 鈥渁llowed to take hold and persist.鈥� It said 鈥渟ystemic failures鈥� meant chances to correct the error were missed,
鈥淭he findings of this report are stark. It details serious failings by individual MI5 officers, resulting in false evidence being provided to the courts, and criticism of MI5 as an organization,鈥� Mahmood said.
鈥淢I5 plays a critical role in keeping our country safe and we owe a debt of thanks to its staff. They have made significant progress over the last year in learning from these failures, but there is more to do to ensure the highest standards of integrity and accountability are upheld.鈥�
MI5 Director-General Ken McCallum said the agency 鈥渞ecognizes without hesitation the seriousness of our failings鈥� and was working 鈥渢o ensure we never find ourselves in this position again.鈥�
鈥淭he people of MI5 work day and night to keep this country safe. We get much right. In this instance we fell well short of what the public expect and deserve,鈥� he said.
Agent X’s former partner, who was identified in legal proceedings only as Beth, said male violence against women 鈥渋s always unacceptable, and all the more so when it is actually enabled by those in positions of power.鈥�
She added: 鈥淲hat today鈥檚 report suggests to me once again is that institutions like MI5 always protect their own.鈥�
In a separate case last year, a report found that MI5 protected a when they knew he was wanted by police for murder, and continued to suppress the truth about the agent decades after 鈥檚 bloody conflict.
