"Unfortunately, we have had to ask Teresa and Rutger to withdraw from the Priodas Pymtheg Mil programme competition.
"There was an accidental breach of the guidelines relating to the encouragement of others to vote.
"This means that the voting process has been compromised.
"In fairness to the other couple involved, and in order to maintain our viewers' trust in S4C, we have had to take the difficult decision to end the competition.
"We wish Teresa and Rutger all the best for the future, and we are offering them our support in light of this development.
"We look forward to fulfil the wedding wishes of the successful couple, Aled and Malin, later this year."
