German Chancellor Angela Merkel has called for younger members of her party to fill ministerial positions in the new government.
She also defended “painful” concessions made to the centre-left Social Democrats (SPD) to clinch a coalition deal.
The deal followed months of wrangling after an inconclusive election.
However it still needs to be approved by the SPD’s 460,000 members, with the result due in March.
On Friday SPD leader Martin Schulz abandoned a plan to serve as foreign minister in the new government, saying he did not want debate about his role to jeopardize the new coalition.
