LONDON, June 23 (Reuters) - European shares climbed to a three-week high on Tuesday, extending the previous session's rally on expectations that Greece was getting closer to a debt deal.
Greece's ATG share index rose 4.2 percent, adding to a 9 percent surge in the previous session, while the country's benchmark banking index was up 7.3 percent.
The Athens' ATG index remains down by around 5 percent since the start of 2015, due to Greece's ongoing debt problems, but it has recovered from a slump last week.
The euro edged back as currency traders cited a range of still-formidable political barriers to a Greek debt agreement this week, but many investors were confident of a resolution.
Greece presented new budget proposals that euro zone leaders welcomed as a basis for a possible agreement to unlock frozen aid and avert a looming default.
"It now appears that we will have a short-term solution to the problems," said Andreas Clenow, hedge fund trader and principal at ACIES Asset Managemement.
The pan-European FTSEurofirst 300 index rose 1.1 percent while the euro zone's blue-chip Euro STOXX 50 index - which had risen 4.1 percent on Monday in its biggest one-day percentage gain since August 2012 - also climbed 1 percent.
Clenow expected a compromise to the Greek debt situation to push European markets back up to peak levels reached earlier in March and April, with the FTSEurofirst still up around 16 percent since the start of 2015.
Numericable-SFR edged back 1 percent after France's economy minister said Altice's bid for Bouygues Telecom risked creating an operator that was "too big to fail" and could threaten jobs, hardening his government's opposition. Altice is the majority owner of Numericable-SFR, France's second-biggest telecom operator.
However, France's broader CAC equity index rose 1.2 percent to go back within sight of its highest level in more than seven years, as a resurgence of activity in France helped euro zone businesses expand at their fastest rate in four years this month.
