It was a tricky one, this. Ten had so many long term and one off companions that it was bound to get people asking where X was and why Y wasn't included. None of his one off companions were included this time, but they won't be missed out on and will be appearing in tomorrows poll.
Anyways, with that out of the way it is time to get on with the results of Ten's companion poll.
Mickey Smith received 2% of the votes
Sarah Jane Smith received 3% of the votes
Captain Jack received 9% of the votes
Martha Jones received 12% of the votes
But in a massive landslide, taking 74% of the votes is Donna Noble, who is going through to the ultimate companion poll with Susan, Jamie, Jo, Romana1, Tegan, Peri, Ace and Rose.
Despite turning down the chance to travel with the Doctor after her first meeting with him, Donna realised what she missed out on and hunted him down. After a year of travels, Donna was forced to leave the TARDIS in one of the most emotional companion exits ever.
