Even if the Prime Minister was able to secure the support of the European Union for her proposals, which is highly unlikely, it is hard to see how they will be accepted by the House of Commons, particularly as the Labour Party has one strategy only - to force an early general election.
"We have time in these negotiations, we have changed tack once and we can change again", he said.
As noted by the BBC, some critics of Theresa May regard Johnson, a former London mayor, as a possible successor, should she be forced out over Brexit.
Turmoil over Brexit plans has hit the pound.
Labour's David Lammy said: "Boris Johnson's after-dinner speaking fee must have plummeted faster than the pound after that dreary, self-important resignation speech".
"We dithered and we burned through our negotiating capital", he said, noting the agreement to pay billions of pounds to settle Britain's financial commitments before any deal on future trade. We must try now because we will not have another chance to get this right'.
The trade bill gives the government powers to adapt national legislation to comply with existing accords, establish new structures to fight any possible disputes following Brexit, and transpose into British law some 40 European Union trade agreements, which the United Kingdom wishes to maintain until it can sign new treaties.
"I understand she's also criticised me for looking for a solution that is workable, I have to say I disagree with her on that - I think what we need is a solution that is going to work for the United Kingdom to ensure we leave the European Union and embrace that bright future".
May's plan has drawn criticism from members of her party as well as pro-Brexit members.
May narrowly avoided a defeat in parliament at the hands of the pro-EU lawmakers from her own party in Tuesday's vote, helped by four opposition Labour lawmakers who went against their party to support the government.
And what will be viewed as a call to arms among his Brexiteer colleagues on the backbenches, Mr Johnson demanded Mrs May return to the proposals she set out in her Lancaster House speech in January 2017.
In a withering assessment, the former Foreign Secretary told MPs that Britain is heading for "economic vassalage" and warned that "a fog of self-doubt" has descended over the prime minister's premiership.
May also sought to rally support in later meetings with Conservative Party backbenchers known as the 1922 Committee and with the Parliamentary Liaison Committee that includes the leaders of all the House of Commons select committees.
A Conservative MP has turned on his Prime Minister - Conservative leader Theresa May, submitting a "no confidence" letter.
The Prime Minister dismissed the charge before insisting she was seeking a "workable" solution to issues with the EU.
Reacting to the vote on Twitter, Lucas said the rejection of the amendment "means MPs in other countries will have more powers of scrutiny than British MPs".
