What to know about the U.K. election, with Labour forecast to knock out Conservatives

July 4 may be Independence Day in the United States, but it’s Election Day this year in the United Kingdom. On Thursday, British voters will elect a new prime minister and Parliament — and polls suggest it will be a landslide.

Prime Minister Rishi Sunak's Conservative Party is forecast to lose big. He may even become the first sitting prime minister to lose his own seat in parliament. And the opposition Labour Party is expected to form the next British government.
