Jeremy Hunt has claimed Angela Merkel is willing to look at new Brexit proposals put forward by the next Prime Minister.
The Foreign Secretary said the German chancellor had told him she would consider any packages put forward as she wants to “solve this problem”.
“Providing we're sensible, and I think the approach that I've laid out is a sensible approach and a fair approach, and I think that it's in Germany's interests as well,” he said.
“What she has said is she will look at the package and I think she will look at it with an open mind.”
Both Mr Hunt and leadership rival Boris Johnson have promised to get a better Brexit deal before the October 31 deadline.
However Mr Johnson has pledged to leave the EU by that date “do or die, come what may”.
Mr Hunt has said if he becomes Prime Minister he will decide at the end of September whether to continue pursuing Brexit talks or lock in a no-deal withdrawal.
“We won't blink as a country. That no-deal Brexit is not going to be an opportunity for them to successfully turn the screws on our country,” he said.
“By the end of September, I, as Prime Minister, will make a judgment as to whether there is a realistic prospect of a deal that can get through Parliament in the short-term.”
Earlier, Chancellor Philip Hammond warned the leadership candidates to “stop and think” before making expensive campaign pledges they may be unable to keep.
He said the candidates must ensure they do not get into a “bidding war about spending more and cutting taxes”.
