Dissident was freed by Egypt after campaign by successive UK governments but offensive posts have surfaced

The decision by successive UK governments to campaign for the release and return of British-Egyptian democracy activist Alaa Abd el-Fattah has been called into question after past violent and offensive social media posts came to light.

The dissident’s historical remarks – in which he appeared to call for violence towards “Zionists” and the police – have prompted a widespread backlash since his return from detention in Egypt on Friday.
