Boeing has agreed to plead guilty to a criminal fraud conspiracy charge after the US found the company violated a deal meant to reform it after two fatal crashes by its 737 Max planes that killed 346 passengers and crew.

The Department of Justice (DoJ) said the plane-maker had also agreed to pay a criminal fine of $243.6m (£190m).

However, the families of the people who died on the flights five years ago have criticised it as a “sweetheart deal” that would allow Boeing to avoid full responsibility for the deaths. One called it an “atrocious abomination”.

The settlement must now be approved by a US judge.
