A former Democratic Unionist Party leader has written a letter expressing "regret" to an alleged victim, a court heard during his trial. The ex-MP, who has pleaded not guilty to all 18 charges including rape, submitted the correspondence as evidence in his defense.

The letter emerged during testimony and became a focal point in the proceedings. Prosecutors are examining whether the communication constitutes an admission of wrongdoing or merely expresses sympathy without acknowledging guilt. The defense maintains the language reflects regret over circumstances rather than culpability for the alleged offenses.

The trial involves multiple counts spanning years. The defendant's legal team is building a defense centered on disputing the allegations entirely, though the letter's contents now complicate that straightforward denial strategy. Legal experts note such correspondence can cut both ways in court, potentially influencing jury perception regardless of the defense's framing.

The case carries significant political weight given the defendant's former prominence in Northern Ireland politics. The DUP has distanced itself from the proceedings, with party leadership declining public comment on the ongoing trial.

Witness testimony continues as the court examines the circumstances surrounding each charge. The alleged victim's account remains central to the prosecution's case, with the letter adding an unexpected dimension to the he-said-she-said nature of the allegations.

The trial is expected to continue over several weeks as both prosecution and defense present their full cases. The former MP maintains his innocence despite the letter's language, leaving the jury to interpret its meaning within the broader context of testimony and evidence presented during the trial.
