London -

It is hard to imagine an example of more irresponsible parenting.

This video is thought to show a father sharing a cigarette with his toddler son.

The man repeatedly passes it between them and shows the boy how to drag on it as a woman is heard laughing in the background. The toddler appears to be trying to imitate the way his father holds the cigarette and giggles and claps when he has had a few puffs.

But when he is refused more, he starts to whimper and points to the packet, prompting the man to give him another.

The clip, thought to be filmed in Russia, provoked a furious response when it appeared on video sharing website LiveLeak this week. - Daily Mail
