His boorish behaviour causes them concern!

The boorish behaviour of a certain political authority from Badulla area has become a source of anxiety and concern to the seniors in the government. 

He is said to using uncouth language when referring to both the government and the opposition seniors. Even the jokes this loose-tongued politico cracks are said to be vulgar and offending. 

The government seniors regret that even the party high-ups have not warned the man to guard his tongue. So, they have decided to ostracize him, they say.
