Pentti Arajarvi, who married the Finnish president Tarja Halonen in 2000, was attending a royal dinner in Copenhagen when he was caught on camera apparently looking at his table neighbour’s chest while she wasn’t watching.

Arajarvi wasn’t just caught out by the cameras though: Princess Mary caught him red-handed as she turned back in his direction.

Shocked, the princess appears to cover her chest with the palm of her left hand, while Arajarvi sheepishly looks around.

More than 14,000 people have watched a video of the incident on YouTube.
