Which parties are dominating the Brexit debate?

Analysis of the Brexit debate transcripts by HuffPo UK has revealed the parties speaking the most and those which are punching above their parliamentary weight. Purely in terms of appearances, the Conservatives have been the most vocal, accounting for 41 percent of the debate after four days. As this chart shows though, compared to the number of seats they hold, they have actually been relatively subdued on the matter. On the opposite end of the scale, the SNP, with a 5 percent share of the seats, have weighed in with 12 percent of the appearances.
