@Spabreak mentioned poshy Petronella Wyatt. this from Wiki (no surprise if true)
Between 2000 and 2004, Wyatt had an affair with the then editor of The Spectator and Conservative MP Boris Johnson.[10] Johnson had promised to leave his wife, and the affair had resulted in a terminated pregnancy and a miscarriage.[11] When her mother found out about the affair, she discussed it with the press.[5][10] Johnson was fired from his shadow cabinet post by party leader Michael Howard for lying about the affair, as he had initially categorically denied it.[10][12]
And he has never stopped lying. To us, his wives/mistresses, whoever.
