Thousands protest South Korean president as older conservatives grumble

By Yun Hwan Chae and James Pearson SEOUL (Reuters) - Hundreds of thousands of demonstrators took to the streets of Seoul on Saturday in the fourth straight weekend of protest against embattled President Park Geun-hye. The scandal has rocked Park's presidency and united Koreans in disapproval, culminating in a protest last weekend that saw a million people march on Seoul by some estimates. Saturday's protest was smaller as protest groups also organized demonstrations in regional capitals.
