The vote-count is blank for all the parties in Thirsk & Malton since that election hasn't happened yet.

The example script here makes the following list of parties standing in more than twenty places:

Socialist Labour Party	23	0
Monster Raving Loony Party	27	0
Trade Unionist and Socialist Coalition	38	0
Plaid Cymru	40	29
Scottish National Party	59	59

British National Party	338	72
UK Independence Party	558	99
Conservative	630	627
Labour	631	625
Liberal Democrat	631	630

(for the curious, the English Democrats kept their deposit in Doncaster North; the Liberal Democrats kept all of theirs but I divided by zero in Thirsk; the Conservatives lost theirs in Na H-Eileanan An Iar and Glasgow East; Philip Lardner stood as an independent in Ayrshire North after being deselected from the Conservatives)
