The Defence Secretary has criticised Russia for conducting a "destructive" anti-satellite missile test.
Ben Wallace said the incident "shows a complete disregard for the security, safety and sustainability of space".
"The debris resulting from this test will remain in orbit putting satellites and human spaceflight at risk for years to come," he said.

Mr Wallace was not alone in his criticism, with General James Dickinson, Commander of US Space Command, also condemning the test.
In a post on Twitter, Gen Dickinson said the test showed a "disregard for the security, safety, stability & long-term sustainability of the space domain for all nations".
"#Space activities underpin our way of life and this kind of behavior is simply irresponsible," he said.
