She said he never expressed extremist views to her or hostility or hatred towards others.

But secret recordings taken by Masood's widow Ms Hydara between 2012 and 2016 revealed he was an Isil supporter and that the pair rowed because she believed "kuffar" newspapers, using the Arabic term for a non-believer.

They were played at the inquest, and Masood is heard telling his wife: “I never hear you say there’s anything good in Isil.

"I never hear you say that some of their people might be sincere and genuine Muslims. All you say is that they are bad, they are wicked, they are evil. You even say that they the same as Jews and Sunnis and that is absolutely disgraceful.

“You seem to believe all this propaganda. Stop being a sheep. Think for yourself. I really do not see eye you eye with you on this issue. You make me made. I am furious."
