Conservative leadership hopefuls should not be described as "Leavers or Remainers", according to Tory MP Damian Green.
The MP for Ashford said until the terms were ditched, the country would be stuck in a Brexit "cycle".
"I think that if all we do is allocate people as Remainers of Leavers depending on what they did in 2016 then we will never get out of the cycle," he told talkRADIO's Julia Hartley-Brewer.
Mr Green has previously been criticised for announcing his support for Matt Hancock - who voted to Remain - in the leadership race.
Defending his position, Mr Hancock said it would be "better" to have a leader who voted Remain to deliver Brexit.
Mr Green added: "I am supporting Matt Hancock because he is a fresh face with fresh ideas which we need in the other areas once we have got Brexit done."
"I think Matt Hancock has got the best set of ideas."
And he slammed the idea of a second referendum, which he said would be "divisive without being decisive".
"I am not attracted by the idea of a second referendum which I think would be divisive without being decisive. It would lead us where we are now, having had another divisive campaign.
"We've got to both deliver Brexit to meet that demand and think beyond that, think to the future."
