Emiliano Sala controversy

Willie McKay helped broker the deal to take Nantes forward Sala to Cardiff City and arranged the flight to take the Argentine to Wales.

After signing for Neil Warnock's side, Sala returned to Nantes to collect his belongings and bid farewell to teammates before heading back to the UK.

Mr McKay, who had met with Sala’s family, said Cardiff were also aware of the travel arrangements for the player.

Sala had asked in a message how much the flight would cost him, however, he was told it would cost him nothing.

The originally scheduled pilot of the ill-fated plane, David Henderson, 64, was arrested in connection with alleged manslaughter after drafting in unqualified David Ibbotson to fly the aircraft.
