Labour MP Jamie Reed sugar coats it:

“Let’s be clear about what happened to Labour and the country on May 7: it was an absolute f*cking disaster.

If anyone in our party seeks to deny the scale of this defeat, they should seek immediate help. If others also seek to claim that they did not see this defeat coming, they too should check themselves in. This defeat was avoidable. A weak government was there for the taking, yet Labour never shifted the needle. As painful as our defeat has proven to be, anyone on the centre-left feeling surprised should probably leave politics now.”
