Or more precisely that the government should be firing the Spanish company that owns Heathrow, with a well-deserved reputation for incompetence (they were forced to divest Gatwick and Stansted). That said, the government is even more incompetent than Heathrow, as shown by the shambles at DVLA or the IR35-linked shortage in HGV haulers, so the incompetence goes well beyond Brexit and it is highly unlikely anyone chosen to replace Heathrow management would be even worse.
