The government is asking a court to force Google to sell its Chrome web browser after the company was found to have an illegal monopoly in search.

In a court filing on Friday, the government signaled a continuation of tough regulatory pressure on the search giant.

Google will have to break up its business, the Justice Department said in a filing, upholding the previous administration's proposal after a federal judge ruled last year that the company illegally abused a monopoly over the search industry.
