In the service, a penitent Charles will acknowledge and solemnly bewail his “manifold sins and wickedness” and promise to be faithful to Camilla. —Paul Majendie —Charles, Camilla Finally Tie Knot After 35 Years (Yahoo!)

Awkward grammar. While the author obviously meant “promise” as a verb, if you take “promise” as a noun, it seems to be the object of “bewail,” suggesting that at a solemn religious service, the Prince of Wales will bewail his promise to be faithful to his new wife.
