In May the Labour MPs wife, Labour councillor Jo White, was sent a dead bird through the post. In August, MP John Mann nearly crashed his car after anonymous sabotage of his car. A car wheel nearly fell off after it was loosened and the hub cap was screwed back on to hide the sabotage.
The number of people pissed off enough by the politicians to make an attempt on one of their lives is uncountable.
