Aer Lingus boss Christoph Mueller has been announced as Malaysia Airlines chief executive-designate.

Last month, MAS posted its worst quarterly loss since late 2011, as passenger numbers and average fare yields fell sharply.

The Malaysian airline has been hit by two disasters this year - the loss of flight MH370 en route to China and the destruction of flight MH17 over Ukraine with the loss of 298 lives.

Mr Mueller ends his tenure with Aer Lingus on the 1st of May.
