There’s a contradiction only because you’re melding the 2 sentences as if they were in the same register.

“The getup of MP Magid Magid in the European Parliament is without a doubt one of the reasons why Brexit is such a disaster. So refreshing to see elected officials who look like us!”

The second sentence is entirely sarcastic, don’t try to fold it in to the other. Whether you agree with the opinion or not 🙂
