A Canadian porn actor has been sentenced to 25 years in prison for murder for killing and dismembering his lover in 2012.

Jurors in Montreal rejected Luka Magnotta's defence that mental illness meant he was not responsible.

Magnotta, now 32, had earlier admitted killing 33-year-old student Jun Lin before his body parts were posted to political parties and schools.

Magnotta was later arrested in a cybercafe in Berlin, Germany.
