Poland's parliament

Armed with European flags in hand, thousands of protesters have marched across Poland this week in opposition of a law that could allow the government the power to fire and control the judiciary if it disagrees with its court reforms.

And in Hungary's local elections, the opposition retook power in Budapest and won mayoral races in 10 other cities.

The question now is whether these results augur a broader political shift in the region.

Polish President Andrzej Duda has announced he is vetoing a controversial law to replace Supreme Court judges with government nominees, according to BBC.

Three key judicial reforms have been passed by Poland's parliament, prompting days of demonstrations across the country.

Before they became law, they required approval by the president.
