Prince Charles remained silent over a question about Prince Andrew during a visit to assess Storm Arwen damage.
The Prince of Wales was unwilling to comment on the ongoing legal battle the Duke is embroiled in with his accuser Virginia Giuffre.
It comes after a judge decided he would have to face a civil trial on sex abuse allegations.
Virginia Giuffre claims Andrew's pal Jeffrey Epstein forced her to have sex with the royal on three occasions when she was 17.
The Duke of York vehemently denies the allegations.

She told the Sun Online: "If the Queen asked Prince Charles and Prince William they would have been very firm, Prince William and Prince Charles have been absolutely furious with him bringing the Royal Family into disrepute.
"Whatever he may or may not have done he certainly was a friend of Epstein and invited him to parties, royal parties when they knew he had been accused of having relationships with underage girls.
"So there’s no doubt about that. I would imagine that this time the Queen would also listen to her aides."
