The driver, 66, crashed the couple's Citroen C-3 after high-speed chase in Spain
He had been driving down the wrong side of a motorway near the village of Jafre
It was then that Spanish officers found his boyfriend's decomposing corpse
He has since told investigating Spanish police officers he was fulfilling one of the items on the 88-year-old's bucket list - to go on a road trip around Europe
