Matt Jeffery, a young father from Somerset, was killed by a single punch on a stag weekend in Laganas, Zante, in 2019. Greek police charged two men from Essex, and one was jailed for twelve years. Our investigation re-examines the video, the court papers and the police statement the conviction rested on, and asks whether the man who threw the fatal punch was ever in the dock. The companion piece to the Sky News documentary The Punch.
