Boris Johnson's former-Svengali Dominic Cummings has set up a new technology consultancy firm three months after he sensationally quit No. 10. Mr Cummings is the director of Siwah Ltd. which was founded on February 25, according to its Companies House listing. It is not clear exactly what the firm will do, but its 'nature of business' is listed as 'information technology consultancy activities'. Boris Johnson's former top-aide Mr Cummings resigned in November last year after the PM's fiancee Carrie Symonds reportedly blocked the promotion of his right-hand man Lee Cain following months of civil war on Downing Street. During his time as Mr Johnson's most-senior official, Mr Cummings issued a clarion call for 'weirdos' and 'misfits' to work in No. 10.
