This CCTV footage shows the horrific moment a man was knocked to the ground by his love rival, resulting in head injuries which killed him a week later.
Matthew Welford confronted Alexander Frew on June 4 this year because he suspected him of having an affair with his wife Sarah.
But after a heated row, Frew, 44, punched Mr Welford, 41, which caused him to fall to the ground and hit his head, leading to a 'massive brain injury'.
The father of two died in hospital eight days after the fight in the car park of the Garforth Country Club in West Yorkshire.
Frew, a train conductor, was today jailed for three and a half years after a jury at Leeds Crown Court found him guilty of manslaughter.
The court heard during the week-long trial that Frew and Mrs Welford had twice stayed in a hotel together.
He insisted that they had not had sexual relations, but admitted that they ended up kissing during the second visit.
Passing sentence, judge Geoffrey Marson said: 'It is perfectly obvious that Matthew Welford believed you were attracted to his wife and as a result there were a number for confrontations before June 4.
The court heard that during previous run-ins Frew had tried to calm the situation, but the pair had confronted each other several times on the day of the fatal argument.
Mr Welford had told Frew 'to keep away from his wife and stop looking at her' and to go looking for sex elsewhere.
During the trial, country club member Kenneth Carter said he heard Frew say: 'I'm waiting for him to come outside. I'm going to have him.'
However, the defendant said that the only reason he punched Mr Welford was because he feared his rival would head butt him.
Mr Marson said: 'The fall caused a massive brain injury of which Matthew died several days later.
'Cases such as these are very difficult. It is not suggested that you intended either to kill or cause Matthew serious harm but the consequences in this case were unintentional and unintended.
'The sentence must be based on what you did, your culpability and the consquences of your unlawful act. The sentence is not meant to be the measure of the value of a human life. No sentence can ever do that.
'I accept you are remorseful and you will have to live with what you did for the rest of your life.'
Mr Welford's family said in a statement after the case: 'Matthew's death in such sudden and tragic circumstances has had a devastating effect on the family.
'When we visited him in hospital he was unrecognisable and we can't get those haunting images out of our heads.
'Our message to people is to be the bigger person and use their common sense. If you get into a situation with someone then just walk away. That other person is someone's son, father, brother and just a moment of violence can ruin their life and yours forever.'
Detective Chief Inspector Nick Wallen, of West Yorkshire Police, said: 'This is a truly tragic case. It demonstrates all too vividly the very grave consequences of throwing that one punch.
'A moment of madness has left a man dead and another man's life in ruins. Never was there a clearer example of why, no matter what the perceived provocation, it is always better to take a deep breath and turn and walk away.'
