Is this a Linnet?

Please could anyone confirm if this bird is a Linnet? I took the photo today on a farmland walk around in East Warwickshire near to a small patch of set-aside which attracts Linnets and Yellowhammers. I am wary of making a definite identification as a Linnet because of the lack of streaks on the breast and what appears to be a yellowish bill. The photo has been cropped quite a bit.
