Chinese university students have been putting up posters criticising their government for amending the constitution to allow Xi Jinping to stay in office as President indefinitely.

The posters feature phrases such as “not my President” and “I disagree” written in both Chinese and English.

They have been spotted at several Western universities outside of mainland China, including the UK, the US and Hong Kong.

In the UK, they were posted at the London School of Economics and the University of Edinburgh.

In a wide-ranging crackdown on online speech around the decision, China banned reference to George Orwell’s novels Animal Farm and 1984, and also the letter “N”.

Other phrases blocked on Sina Weibo, China’s equivalent of Twitter, included “disagree” and “Xi Zedong,” a combination of Mr Xi’s and Mao Zedong’s names.

The phrase “not my President” has been used during protests in the US against Donald Trump.

The posters initially appeared in several universities across the US after a Twitter account, @StopXiJinping, posted links encouraging people to download the posters.

Since then, the account has drawn attention to universities where the posters have been put up.

Those behind the account, which has over 3,000 followers, told the BBC they were Chinese university students living abroad who wished to remain anonymous.

“Which is unfortunate because expressing your dissent ideas is a matter of dignity. However, free speech is protected in Western countries, which is where our campaign has lifted off.”

The organisers did not respond to The Independent’s request for comment.

China’s parliament passed the constitutional amendment to scrap a two-term limit and further strengthen the Communist Party’s dominant role in politics.

Only two “no” votes were cast, with three abstentions and one vote invalidated, among nearly 3,000 delegates.
