Prime Minister Yoshihide Suga pledged Sunday to lead Japan's ruling Liberal Democratic Party to victory in this year's general election, as speculation swirls over when he will dissolve the House of Representatives.

The comments at the LDP's annual convention in Tokyo came amid a slight improvement in the approval rating for Suga's Cabinet, recovering ground lost amid criticism of the government's COVID-19 response.

"Our party is the only one that can overcome the national crisis of the novel coronavirus and protect the Japanese traditions created by our forebears, and pass on this country to the next generation while valuing diversity and creativity," the prime minister said.
