Mohamed Ali (also: Aly; born 19 January 1978) is an Egyptian building contractor living in exile in Spain who worked for 15 years with Egyptian president Abdel Fattah el-Sisi and Sisi's colleagues building villas and a palace.
In September 2019, Ali circulated videos accusing Sisi of corruption.
The online circulation of videos snowballed, with others including Wael Ghonim joining in the anti-Sisi criticism.
Ali called for mass anti-Sisi street protests which started on 20 September 2019 across Egypt.
