The TV presenter shared his thoughts after the Prime Minister confirmed that he was stepping down, saying in his speech how sad he was to give up “the best job in the world" but that "them’s the breaks".
Morgan had been outspoken in the run up to the announcement, saying it was time for Johnson to go and taking a pig on his talk show for emphasis.
And he didn’t hold back when it came to commenting on the politician’s speech, tweeting: “Boris Johnson quits as he led - boasting, blathering & blaming everyone but himself.
“What a terrible final speech by a man who turned out to be a truly terrible Prime Minister.”

While many of Morgan's followers voiced their agreement, others said they thought Johnson was "gracious" and "articulate" in explaining his decision.
Some people quipped that they could see parallels between Johnson's exit and his own departure from Good Morning Britain.
One fan tweeted: "Sounds quite similar to your departure from breakfast tv?"
Another joked: "Least he didn't run away Piers like someone one we all seen on GMB."
Clutching a pig, he said he didn't think anything could be done to save Johnson's bacon.
