The British government said on Thursday that it would allow 16- and 17-year-olds to vote, in what it called a landmark moment for democracy and some of its opponents decried as an attempt to tilt the electoral playing field. Britain has more than 1.6 million people of age 16 or 17, in a total population of roughly 68 million, and the plan has been described as the country’s largest expansion of voting rights in decades. The last nationwide reduction in voting age, to 18 from 21, came more than 50 years ago. “Declining trust in our institutions and democracy itself has become critical, but it is the responsibility of government to turn this around and renew our democracy, just as generations have done before us,” the deputy prime minister, Angela Rayner, wrote in an introduction to a policy paper that included the announcement. The plan also includes promises to tighten laws on foreign donations to political parties, and to simplify voter registration.
