Concessions are possible for Greece so long as Prime Minister Antonis Samaras shows a willingness to meet the main targets set out in his country's bailout program, a senior lawmaker with Chancellor Angela Merkel's party said.

A precedent for program adjustments was made with the first Greek bailout, when the country secured lower interest rates and longer maturities on bilateral loans than those originally set, Norbert Barthle, the Christian Democratic Union's budget spokesman in parliament, said today in a telephone interview.

“Small concessions are feasible provided they are strictly made within the framework of the second aid program,” Barthle said. “For instance, the interest and maturity on loans could be adjusted, as in the case of the first aid package for Greece.”
