From the Guardian:
The rehearsals, portentous theme tunes, garish computer graphics, live links and guests had not prepared for such an SNP tsunami and the decimation of the Liberal Democrats
As Baroness Hussein-Ece has pointed out, thousands of people have died tragically as a result of tsunamis. It is a terrible insult to their memory to compare a event where no one died to such tragedies.
Decimation means the elimination of one in ten of a population. The Liberal Democrats lost nearly nine out of ten of their MPs. That is not decimation. (Although I admit the dictionary has moved with the times on that one – it just annoys me that people don’t find a word with a more appropriate original mathematical co-relation!)
That is all.
