British opposition Labour leader Jeremy Corbyn said on Sunday people convicted of terrorism offenses should "not necessarily" serve their full prison terms because it depended on the circumstances of their imprisonment.
Talking to Sky News, Corbyn also said the police had no choice but to shoot an attacker who killed two people in central London on Friday.
"I think they had no choice. They were stuck with a situation where there was a credible threat of a bomb belt around his body and it's an awful situation for any police officer, any public servant to be put in," Corbyn said.
