Some in the Labour Party want to blame our defeat only on the leadership. Others want to blame it only on Brexit . Yet it was about both of those things and more. In our towns in Yorkshire, we knocked on thousands of doors trying to persuade people to stick with Labour. Some said they just didn't want Jeremy Corbyn to be Prime Minister. Others were fearful that we wouldn't stand up for national security. Some wanted Brexit done and felt angry and let down. We found little enthusiasm for Boris Johnson. One woman told me in tears that she was voting Tory for the first time and she was furious with us for making her feel like she had to do it.
