This meant that, no matter how many public votes were cast in their favour, it was mathematically impossible for the third-placed couple to remain in the competition. This oversight was initially unnoticed by producers until after the public vote became live and viewers were invited to call in and save their favourites at a cost of 15p per vote. Once the mistake was finally realised and the public vote was closed, it was announced that all three couples would be put through to the final, all the votes already cast would count towards the final result of the competition, and viewers could apply for a refund if they wished.

Ofcom also opined that "the BBC had been open and transparent with viewers about the mistake it made and the solution adopted".

This was later confirmed by the BBC in July of that year. Subsequently, the BBC was accused of ageism and sexism by several sources, an accusation the corporation has faced before over the removal of several older female presenters, including Moira Stuart, Juliet Morris, Miriam O'Reilly, Michaela Strachan, Charlotte Smith and Anna Ford. The BBC denied the allegations that the decision to remove Phillips was due
