Sir Keir Starmer has said closer ties with the EU will be good for the UK's jobs, bills and borders ahead of a summit where he could announce a deal with the bloc.
The government is set to host EU leaders in London on Monday as part of its efforts to "reset" relations post-Brexit.
A deal granting the UK access to a major EU defence fund could be on the table, according to reports - but disagreements over a youth mobility scheme and fishing rights could prove to be a stumbling block.
The prime minister has appeared to signal a youth mobility deal could be possible, telling The Times that while freedom of movement is a "red line", youth mobility does not come under this.
His comment comes after Kaja Kallas, the EU's high representative for foreign affairs, said on Friday work on a defence deal was progressing but "we're not there yet".
Sir Keir met European Commission president Ursula von der Leyen later that day while at a summit in Albania.
If agreed, the deal will be the third in two weeks, following trade agreements with India and the US.
Sir Keir said: "First India, then the United States - in the last two weeks alone that's jobs saved, faster growth and wages rising.
"More money in the pockets of British working people, achieved through striking deals not striking poses.
"Tomorrow, we take another step forward, with yet more benefits for the United Kingdom as the result of a strengthened partnership with the European Union."

Conservative leader Kemi Badenoch has said she is "worried" about what the PM might have negotiated.
Ms Badenoch - who has promised to rip up the deal with the EU if it breaches her red lines on Brexit - said: "Labour should have used this review of our EU trade deal to secure new wins for Britain, such as an EU-wide agreement on Brits using e-gates on the continent.
"Instead, it sounds like we're giving away our fishing quotas, becoming a rule-taker from Brussels once again and getting free movement by the back door. This isn't a reset, it's a surrender."
