Imran Ahmed, an anti-disinformation advocate, claims he is being targeted for scrutinising social media companies

A British anti-disinformation campaigner close to Keir Starmer’s chief of staff has launched a legal challenge against the Trump administration after being told he could face deportation from the US in a row over freedom of speech.

Imran Ahmed, the chief executive of the Centre for Countering Digital Hate (CCDH), has filed a complaint against senior Trump allies including the secretary of state, Marco Rubio, and the attorney general, Pam Bondi, in an attempt to prevent what he says would be an unconstitutional arrest and removal.
