King Charles has sent a heartfelt message to the President of Greece following a tragic train crash in the north of the country.
More than 40 people were killed in the head-on crash involving a passenger and freight train on Wednesday, with rescuers still searching the wreckage, and over 50 people being treated in hospital.
Expressing his sorrow in a letter to Katerina Sakellaropoulou, Charles wrote: "Dear Madam President,
King Charles has expressed his sorrow after the tragedy in Greece
"My wife and I have been most shocked and profoundly saddened by the news of the dreadful accident involving two trains in Northern Greece and would like to express our deepest possible condolences to the families of all those who have so tragically lost their lives.
"During our visits to Greece we have always been struck by the kindness and generosity of the Greek people and our thoughts, prayers and heartfelt sympathy are with all those who have been affected by this appalling tragedy." He signed the letter, Charles R.

'I am devastated by the thought of the unmeasurable pain the parents are going through, who lost their children so unfairly. God bless them and give them strength.'"

Charles and Harry's relationship remains very strained
Charles's heartfelt message comes hours after it was confirmed that he has requested Prince Harry and Meghan Markle vacate their UK home, Frogmore Cottage.
Neither the monarch, nor the Sussexes, have commented on the decision, which was said to have been made shortly after the release of Harry's explosive memoir Spare in January.
Following the move, the question of Harry and Meghan's attendance at the coronation on 6 May remains up in the air.
