Title and abstract of a journal article: "Eyes and ears, and potentially so much more: the role of parliamentary private secretary to the prime minister—a case study".
Reading London Playbook ("The PM seems confident, which is why he got his PPS to text all Labour MPs last night begging them not to sack him / giving important context on the Mandelson case") has reminded me: this just came out (doi.org/10.1093/pa/g...). Possibly of interest to Thatcher 'fans', too?
