Ahead of Tuesday's meeting of the National Executive Committee, large numbers of Labour MPs and candidates and leaders of major unions called for the party to back a referendum on any Brexit deal.
Jeremy Corbyn has seen off an attempt to commit the party to a confirmatory referendum on any Brexit deal.
"This is exactly what I thought we would see, and in the coming weeks I fully expect to see support for the Brexit Party increase further", he said.
Labour's governing body - the National Executive Committee - is made up of leader Jeremy Corbyn, members of his shadow Cabinet, MPs, MEPs and representatives from supporting trade unions.
A party spokesperson said: "Labour's European elections manifesto was agreed at the NEC today and it will be published soon".

The meeting came amid increasingly positive mood music surrounding cross-party Brexit talks with Labour, with the Government understood to be hoping a conclusion may be reached towards the middle of next week.
Asked what will happen if Labour goes into European elections without a clear promise on a second referendum, Ms Phillips said: "I think people who voted remain and voted Labour will not vote Labour again".
After failing to persuade many lawmakers from her own Conservative Party to support her Brexit deal, May opened talks earlier this month with Labour.
But shadow worldwide trade secretary Barry Gardiner said it would be a change in Labour's policy, which is to "try to deliver on what people voted for" in the 2016 referendum.
But with a new Brexit deadline set for October 31, parties are readying themselves for the May 23 European Parliament elections, offering those wanting to remain in the EU and others supporting a clean break another potential battleground.
The party is deeply split over the issue.
The latest talks between the government and Labour on Monday were described as "positive" and "productive" by the PM's de facto deputy David Lidington.
