Mr Davey, who is battling with Jo Swinson for the party leadership, made the revelation after speaking to the i. The former Energy and Climate Change Secretary told the paper: “There are some Conservative MPs who are thinking the unthinkable and there are some liberal Labour people who are thinking the unthinkable.” Saying views over Brexit had lead to MPs considering crossing the floor, he added: “I am not going to name any individual names. These are conversations that have been taking place over recent months.”
Pro-Remain party Change UK has recently lost six of their 11 MPs with party leader Heidi Allen, Luciana Berger, Gavin Shuker, Angela Smith, Chuka Umunna and Sarah Wollaston all resigning from the party.
Mr Davey confirmed discussions with the MPs had taken place but added it was vital to “give them time to come to their own decision”.
He went further to explain that he would seek to introduce legislation to change the legal default of the UK failing to secure a deal from going forward with no deal to revoking Article 50.
If this failed, he would then support a vote of no confidence in the Tory Government with a view to form a government of national unity and stage a second referendum.

The Liberal Democrats currently have just 11 MPs in the Commons, this was after the party lost 49 seats in the 2015 general election, dropping from 57 to 8 seats.
The Scottish Nationalist Party also took their position as the 3rd biggest party in Westminster.
However, the party enjoyed success in the recent European elections, increasing from 1 MEP to 16 and trebling their vote from 2014.
Mr Davey has said he will opt not to attempt to capitalise on this surge of support saying: “My driving force at the moment is to stop Brexit, we are not going to do a Boris Johnson, or Jeremy Hunt, or a Theresa May and put party before country.
“We are going to put country before party and that is to stop Brexit in a democratic way.”
The six recently resigned MPs who defected from Labour and the Tories to Change UK were joined by Ann Coffey, Mike Gapes, Chris Leslie, Joan Ryan and Anna Soubry.
Excluding the Change UK group, the last two times a Conservative MP left the party and directly joined another occurred in 2014 with both Douglas Carswell and Mark Reckless joining UKIP.
For Labour, the last time was in 2005 when Brian Sedgemore joined the Liberal Democrats, Mr Sedgemore’s resignation came after Parliament was dissolved for a general election in which he did not stand.
The last time a Labour MP left the party and joined another party without first sitting as an independent before this was in 2001 when Paul Marsden joined the Liberal Democrats following opposition to the war in Afghanistan.
Mr Davey and Ms Swinson will standoff in a ballot by party members to succeed Vince Cable as party leader with the winner being announced on July 23rd.
