An amusing video has emerged of a bride saving her groom from falling off a cliff during a ceremony in the USA.

Faith and Peter Bolton were originally married in 2009 and decided to renew their vows, in front of friends, on top of a mountain in Santa Fe, New Mexico last month.

Peter can be seen reading his vows when he loses his balance and leans perilously backwards over the precipice.

Fortunately Faith was able to lean forward to catch him and the wedding party was later able to laugh about the near-miss.
