Australia's Prime Minister Scott Morrison's Liberal Party lost access to his official WeChat social media account months ago, politicians said on Monday, issuing claims of censorship, while the still-active account being run by a new Chinese controller now promotes Chinese life in Australia.

Amid growing diplomatic tensions with China, Australia's two major political parties have used the social media platform, owned by Chinese tech giant Tencent Holdings Ltd, to communicate with Australian voters of Chinese ethnicity in tightly fought electorates since 2019.

With a national election due by May, the government would have aimed to use the Morrison account to promote its policies during the Chinese New Year celebrations starting Feb. 1. The prime minister's office has made multiple fruitless requests to WeChat to regain access to the account, most recently on Jan. 10, said a person with knowledge of the matter, who declined to be named because of the sensitivity of the matter.
