As first brought to Y-H-B’s attention by Jacobus Primus, speakers on both sides of the Atlantic are increasingly prone to confuse the phrases on behalf of and on the part of, using the first when they mean the second. This mistake was heard being made by an otherwise RP speaker this morning on the BBC World Service, which can be taken as a warrant of its pervasiveness.

A confusion of this sort is significant not only in itself but as a sign of a failure of thought, illustrating yet again the role linguistic error plays in undermining the cognitive integrity of verbal communication.
