Objectives: Our task is to describe the speech component of image structure on the example of an established, conceptually concise image (Margaret Thatcher). Methods: Systematization and theoretical understanding of the material. A descriptive method for creating biographical context of understanding Margaret Thatcher's career. Method of diagnostic context, denotative, emotive and structural analysis, semantic differential. Corpus-based and cross-lingual methods. Findings: The research of corpus of Margaret Thatcher's texts suggests that Thatcher's speech image is a combinatorial formation based both on the process of the personal potential exteriorization (the image of "the Iron Lady"), and the verbal behavior program setup implementing the communicative ideal of a mother. Applications/Improvements: Application of the results includes linguo-pragmatics, political linguistics, sociolinguistics, discourse theory and practice.
