George Freeman has refused to be drawn on who his preferred candidate is to become the new leader of the Conservatives.
The MP for Mid Norfolk had previously backed Penny Mordaunt in the race to be the next prime minister, even running her campaign.
But Ms Mordaunt was eliminated in this week's final vote, leaving former chancellor Rishi Sunak and foreign secretary Liz Truss as the final two.
Instead of revealing his preference, Mr Freeman said he was more concerned about the party's wider appeal.
"Both the candidates are competing for the party's vote, but I hope they recognise it is just as important they carry the public support," he added.
"This person is going to have to take big decisions on the cost of living, climate change and international affairs, and they are going to need to carry the support of the public with them.
"I hope Liz and Rishi will campaign not just for Conservative votes, but for the trust and respect of the broader public we are here to serve."
