Millions of voters in Britain are going to polling stations for local elections in what political commentators have dubbed as the Super Thursday, which is seen as a major test for Britain's main political party leaders. More than 5,000 seats are up for grabs in city hall and town hall elections, with the mayor of London and 12 provincial mayors along with police and crime commissioners also being elected.
