British politicians and international organisations have had their accounts on X hacked on Wednesday night.

MPs including Shabana Mahmood, the justice secretary, and the Labour MPs Chris Elmore and Carolyn Harris all shared the same message on the social media site. Although quickly removed, the messages could still be read on TweetDeck, a dashboard used to manage accounts on X, formerly Twitter.

The messages, which also included a lengthy code, said: “THIS IS HACKED ACCOUNT!!!! INTRODUCING HACKED ON SOLANA on each account we hack we publish the token address so we pump it and make profits together.”

The message on the justice secretary’s account was posted at 7.53pm and had been deleted by 7.55pm. It is not the first time a British politician’s account on the website has been hacked. Jeremy Corbyn’s Twitter account was hijacked in 2016 when a series of expletive-laden tweets were posted.

One aimed an insult at the then prime minister, David Cameron, while another expressed opposition to the Trident nuclear defence programme.

Other accounts that posted the same message on Wednesday evening include the World Health Organization, the Great British Menu and the India branch of the technology company Lenovo.

While many quickly deleted the hacked message, some remained visible for some time. The British comedian and actor Sooz Kempner shared to X that her account was also hacked and she had changed her password.
