The family of Karen McGonigal, 53, who died after receiving fake weight-loss jabs, is calling for a clampdown on the black market for such medications.

One person has been arrested on suspicion of manslaughter in connection with her death. Health Secretary Wes Streeting has warned the public against purchasing weight-loss medications from unregulated sources. Watch the video in full above.
