Richard Cannon, a lawyer for the Grillo sister's said: "My clients are naturally relieved at the verdict of the jury. This has been a long hard fight, played out in the gaze of the world's media.
"Elisabetta and Francesca would like to thank their friends and relatives for their love and support. Additionally they'd like to thank those members of the public who've expressed their best wishes. Finally they have asked me to thank their legal team for all their hard work."
