The marriage of the two strangers who won the competition is to go ahead as planned despite efforts to sabotage the event, its organisers said last night.
Birmingham-based station BRMB said it was disgusted at a third party's attempt to show a picture of groom Craig Cooper to his bride, Rebecca Duffy.
The pair - who first spoke to each other on Friday - are set to meet for the first time today when they tie the knot following their victory in BRMB's Two Strangers and a Wedding II contest.
Howard Bradley, BRMB's marketing director, said he was "incensed" that someone had tried to disrupt efforts to ensure the couple did not see each other until the ceremony.
"All we know is that someone had a picture of the groom, Craig, and was trying to find where Becky was to confront her with the picture," Mr Bradley said.
"Fortunately we discovered this and Becky will see Craig only at the ceremony. It may be either a disgruntled finalist or someone opposed to the idea, or a journalist - whoever they were they haven't succeeded and the wedding will go ahead as planned."
Miss Duffy, 28, and 30-year old Mr Cooper beat off competition from more than 250 other hopefuls to secure the chance to wed.
The unusual union - which has been attacked as an immoral publicity stunt by Church leaders - will take place at Birmingham's Hotel du Vin.
Billed as the ultimate blind date, Two Strangers and a Wedding was first held by BRMB in 1999. The winners of the original contest - Greg Cordell and Carla Germaine - split up just three months later.
Mr Bradley said Craig and Rebecca were chosen because they were "real" people.
"The decision was not taken lightly and everyone is committed to the success of this marriage - not least the couple themselves. Craig has said that he's already looking forward to the 'first ten years'," he said.
"It is our belief that this marriage will succeed and the couple will have a great start to their wedded life and BRMB will be with them throughout the first year and beyond."
