The reigning I'm A Celebrity champion has said Matt Hancock should expect the public to use him as a "toy" before voting him off the show.
Miller, who is best known for his role as Aaron Livesey on the ITV soap drama Emmerdale, commented on Hancock's likely future as a contestant, in an interview on Good Morning Britain.
Hancock, the MP for West Suffolk, had his Tory whip suspended after agreeing to be a contestant on the reality TV show, during a time when Parliament is in sitting.
The reigning "King of the Castle" predicted the audience to vote for Hancock's participation in all the show's gruelling eating challenges.
"I think he needs to just accept the fact that he is going to be everyone's toy," he said.
In reference to the previous season, Miller reflected on how the public continuously voted for music producer, Naughty Boy to do the show's Bushtucker Trials.
"Last year, unfortunately Naughty Boy got it because he did the first one (challenge) and he was very entertaining and everyone then went, 'Naughty Boy, Naughty Boy, Naughty Boy!'."
Speaking on Hancock, Miller said: "I think regardless of how entertaining he is, he needs to accept that what he has put us through, I think the public are going to say, 'This is what we are going to put you through'.
"And when they are done with him they will just get rid of him, I think."

When asked about his favourites to win this year's series, Miller replied: "I would like to think Sue Cleaver, Boy George and Jill Scott. They are my prediction for the final three."
The show has officially confirmed 10 contestants so far to appear alongside Hancock - who is expected to be one of the two surprise guests to grace the camp in the days after the launch.
Miller even joked about the possibility of former Prime Minster Boris Johnson being one of the final unannounced names to appear on the show.
He said: "I have heard certain things about who it might be and if it is it will be brilliant."
When asked who, he replied: "I can't tell you that. It's Boris Johnson!"
Hancock, 44, will appear in the Australian jungle alongside rugby player Mike Tindall, pop star Boy George, and former Love Island contestant Olivia Attwood.
The former health secretary previously told the Sun that he wants to use the "incredible platform" on the show to raise awareness of dyslexia.
He also insisted that it "wasn't the cheque", which influenced his decision to join the show.
