The bill, which will end the supremacy of European Union law in the United Kingdom, now moves onto its next parliamentary stage but scores of amendments were tabled within hours of it passing its first parliamentary hurdle.
The opposition Labour Party has said it plans to vote against the bill unless the government comes forward with concessions, and has said several clauses in the legislation amount to a "power grab" by government.
Ms Leadsom, who squared off with Theresa May after the resignation of former Prime Minister David Cameron, claimed it would help the party get on with Brexit. None of the Conservatives voted against it.
The bill will now move onto committee stage and undergo line by line scrutiny.
"The UK and the European Union could also continue cooperation in areas where we have common objectives and shared threats, including cooperation and continued support through existing foreign policy mechanisms which serve both UK and European Union partners' interests, such as election observation missions, and conflict management tools..."
The government has promised concerned lawmakers that ministers would not use the wide-ranging powers to make "substantive changes" to law and some have said they will seek changes to the bill at later stages.
European Union lawmakers must endorse any agreement before Britain leaves in March 2019.
The vote followed a disastrous loss for the left-wing leader as his amendment to the bill was also defeated by Labour MPs.
The prime minister won after her government promised to discuss critics' concerns before they have to vote again, and to consider allowing more time for the next stage of debates on the law.
"Labour will seek to amend and remove the worst aspects from the bill but the flaws are so fundamental it's hard to see how this could ever be made fit for goal", the Labour MP said.
The Liberal Democrat Brexit spokesperson, Tom Brake, said MPs who backed the bill should feel "ashamed".
To seek to thwart the country's decision on June 23 previous year, and subsequent majority votes in the Houses of Parliament, would be the ultimate betrayal of democracy.
Labour's Chris Bryant accused May's ministers of ignoring democracy, describing the bill as "utterly pernicious and dangerous".
