"Police chief issues Tory apology" - Curious choice of words for the BBC headline

The BBC's headline for their piece on Met Police Assistant Commissioner Bob Quick's unreserved apology to the Conservative party is peculiar. "Tory apology", why not "apology to the Tory party" or "apology to the Tories"? Maybe this way the BBC can try and associate, for any skim-readers, the apology with the Tory party rather than with the police.

BBC bias or incompetence, you take your pick...
