The task of forming the next German government using an untried coalition looks a tricky task for long-time leader Angela Merkel.
A mooted three-way pact involving the CDU/CSU, Greens and FDP has been dubbed a "Jamaica" coalition because the parties' colors — black, yellow and green — match those of the Caribbean nation's flag.
Exploratory talks between parties began last Wednesday and could continue into 2018 if a quick agreement cannot be found.
Otto Fricke, member of the federal executive board of Germany's FDP, told CNBC Monday that talks were going well enough for now.
"Right now, they have come along as people. If they come along as politicians we will see," said the budget spokesperson.
Fricke added that, as it stands, Merkel has a chance of forming a government.
"If you've lost that much of voters then, of course, you are weakened," he said. "But it is always a question at the end of how your own party is supporting you and that is something where the CDU has been very strong in the last few years.
"If you see the sister party CSU being a little more calm than they were before the election, she has a chance."
