The Labour right wing were fully expecting and hoping for the party to lose a key by-election in Peterborough last week. This constituency voted strongly to leave the European Union, and the press had hyped up Nigel Farage's right-wing Brexit Party, which everybody expected to win the seat. This would've given a boost to the Blairite plotters and Farage's hard-Brexiteer outfit. But on the day, Labour defied expectations and won with an increased majority.
