The British general election results are as close to final as they're going to be, in that the vote in one constituency is postponed, due to the death of a candidate.
Here are the results in 649 of the 650 constituencies (with my predictions in parentheses):
Conservative 306 (300)
Labour 258 (255)
Liberal Democrat 57 (68)
Other 28 (27)
I overestimated Liberal Democrat support. While realizing that the major gains that were indicated by earlier polls would not come about, I didn't realize that the party would actually lose seats.
