The family of Anni Dewani believe they have been failed by the justice system and are "deeply disappointed" after millionaire businessman Shrien Dewani was cleared of the honeymoon murder.

Speaking after the case was dismissed, Mrs Dewani's sister, Ami Denborg said: "Today we feel as a family that the justice system has failed us and we are deeply disappointed.

"We came here looking for answers and we came here looking for the truth and all we got was more questions.

"We waited patiently for four years to hear what really happened to Anni and to hear the full story of what happened to our dearest little sister.

"All we wanted was to hear all the events and the hope of actually finding that out has kept us, as a family, going.

"Unfortunately we believe that this right has now been taken away from us."

An emotional Ms Denborg added: "Today we feel really, really sad, because we never heard the full story of Shrien.

"We heard that Shrien has led a double life and that Anni knew nothing about it.

"And we just wish that Shrien had been honest with us and especially with Anni.

"The knowledge of not ever knowing what happened to my dearest little sister on the 13th of November 2010...that's going to haunt me, my family, my brother, my parents, for the rest of our lives.

"We've had four years of sleepless nights and ...will we ever be able to sleep?

"We've had tremendous support from the South African public, and many others around the world, and we're grateful to all of them and thank them from the bottom of our heart.

"This is a really sad day for us and we hope that no other family will ever have to go through what we have been through."

Ms Denborg said the family will be making no further comments and asked for "time and space for reflection".
