The results include a breakdown by ward. They also include a breakdown by Westminster constituency but they are just about the council elections so although the results show Labour 'winning' the Brighton Pavillion seat in the council elections that does not take into account Caroline Lucas' personal vote.
The Lib Dems contested 45 out of 54 seats in 2011 (Green, Lab and Con all had full slates). They had no candidates in Moulescoomb & Bevenden, and incomplete slates in a few other wards. They came closest to holding a seat in Brunswick & Adelaide.
The 2011 percentages used in the comparison appear to be based on total vote, probably misleading in an authority with a mix of two and three member wards. Rallings and Thrasher using 'top vote' have Con 28.3 Lab 30.9 LD 6.0 Green 31.0.
