Liz Truss’s chief of staff brings key figures from lobbying firm into No 10

Mark Fullbrook asserts grip on Downing Street by giving senior roles to founding members of Fullbrook Strategies

Mark Fullbrook, Liz Truss's new chief of staff, has asserted his grip over Downing Street by bringing senior figures from his lobbying firm into No 10.

The political consultant, a former long-time colleague of election strategist Lynton Crosby, was appointed to the most senior role in Truss's team this week, after previously working on the failed leadership campaign of Nadhim Zahawi.
