Michael Gove has distanced himself from some of the arguments he made during the Brexit referendum, including claims over levels of Turkish immigration.
The Leave campaign was criticised at the time for suggesting Turkey may join the EU by 2020 and up to 5.2m more migrants could come to the UK by 2030.
In a new book, Mr Gove says it "did not get everything absolutely right".
"If it had been left entirely to me, the Leave campaign would have had a slightly different feel," he admits.
The claims about Turkey were strongly rejected at the time by Downing Street, which insisted that its accession was a long way off and that the UK would have a veto anyway.
In an interview for the book, Ctrl Alt Delete, Mr Baldwin asked the environment secretary whether he was entirely comfortable in "appealing to some very low sentiments".
Mr Gove is quoted as replying: "I know what you mean, yes. If it had been left entirely to me, the Leave campaign would have had a slightly different feel.
"I would have to go back and look at everything I said and think whether that was the right response at the right time. There is a sense at the back of my mind that we did not get everything absolutely right.
"It's a difficult one."
Mr Gove is also pressed in the book about his much-quoted claim from the campaign that people had "had enough of experts" telling them what to think about Brexit.
He says the remark was spontaneous rather than intended and designed not to denigrate expertise but to highlight past claims, such as over the 2008 financial crisis, which had been wrong.
"The irony, of course, is that I often cite experts to justify what I am doing," he adds.
Labour are trying to force checkmate. If the government can't get the numbers for either version of Brexit it must spell the collapse of the government. If they can show Mogg is just as weak as May the Tories are toast.
