ATHENS, Greece (AP) — Several thousand lawyers, many wearing ties or high heels, have marched to parliament to protest a planned overhaul of the pension system by the country's leftwing government.

Chanting "No retreat till we're vindicated," the lawyers came from associations around Greece that are calling on the government to scrap key provisions outlined in government proposals this month.

Pension reform in rapidly-aging Greece is a key demand being made by bailout lenders, who are studying the proposals and have argued that current levels of state funding for the pension system are unsustainable.

The pension reforms have drawn broad opposition from various professional groups, with farmers planning protests next week and the country's largest labor union calling an emergency meeting Friday to consider strikes.
