Banns delivered
Dornoch registrar Lesley Conner delivered the wedding banns, which were posted on 6 December, to the couple on Thursday morning.
Under Scots law, a couple getting married must collect the banns prior to their wedding, except in special circumstances such as security reasons.
The Scottish Executive confirmed special arrangements had been made for the registrar to deliver the banns to the couple, to the disappointment of waiting reporters and photographers.
A spokesman said: "In view of the situation, special arrangements have been put in place.
"The couple will not have to go to collect the banns, they are being delivered to them."
However, when Mrs Conner arrived at the registrars office at 0940GMT, she was keeping tight-lipped about the situation and said she was late for work.
