Emma Bache, author of Reading Between The Lines, took a close look at the handwriting of Mr Johnson and former Brexit secretary Dominic Raab. She said: “Boris Johnson’s handwriting is disconnected and fast. He is an intuitive thinker who leaves little room for logic.
He can be impatient with detail but there is intellectual creativity if not stability.
“[He] can be moody and unpredictable and is likely to speak and act without thinking things through. However, there is a sensitivity and an ability to be flexible and adaptable to situations.”
She added: “He surprisingly wishes to be seen as more logical than he really is but is also happy to show off his impatient gung-ho attitude.”
On Mr Raab’s handwriting, she said he displayed “determination but hesitancy and a somewhat unemotional outlook”. She detected a “writer who is torn between friendliness and a more adversarial stance”.
She added: “He very much wants to be liked and accepted by others but is unable to sustain the facade as the capital D is bent and hesitant. His surname is confused, illegible and ends with a distinctive X.
“This could be seen as a kiss but is also indicative of a writer that sees the dark side of life and may be feeling deeply uncomfortable.”
