Misfired bias at the BBC?

Compare the BBC's excerpts from Sharon's speech with the more complete transcript on Arutz 7. The BBC edits out all of the remarks pertaining to Mitzna. This begs the question: what was the BBC aiming for? To portray Sharon in the best light, by making his speech look less controverisal than it was, or to portray Mitzna positively, by shuffling aside Sharon's criticisms of him? Probably the latter.
