LONDON, July 5 (Reuters) - New Prime Minister Keir Starmer said Britain needed to rediscover its identity and undergo a wider reset, in his first words outside his new office at 10 Downing Street, promising to fight to restore trust in politics and serve all voters.

"It is surely clear to everyone that our country needs a bigger reset, a rediscovery of who we are, because no matter how fierce the storms of history, one of the greatest strengths of this nation has always been our ability to navigate a way to calmer waters," he said.
