Convicted killer Graham Dwyer may have to wait until the summer to hear the outcome of his last ditch appeal to overturn his conviction for the murder of Elaine O’Hara.

The judgment by the seven-judge Supreme Court is to be delivered later after it has given a ruling in two appeals raising similar issues about the admissibility of phone data at trials.
