The escalation of the full-scale military conict between Russian and Ukrainian forces in February 2022 initiated a worldwide conversation. The manifestation of diverse opinions about the war on Twitter demonstrates a social phenomenon that reveals peoples' perceptions, thoughts, and interactions with war-related information in a digitalised world. Whereas the majority of media outlets in the UK have been following the events in Ukraine, little is known about people's sentiment toward sending military, nancial or medical aid at the regional level. Therefore, this work is to develop a broader understanding of the UK public opinions through Sentiment Analysis (SA) where we collected 2,893 English-language tweets from Twitter API and additional geolocation data is integrated from external sources. The acquired dataset is preprocessed and prepared for textual analysis. In addition to SA, this work compares and contrasts dierent approaches and four selected ML models. Finally, this work uses data visualisation techniques to demonstrate the results from three perspectives; quantitative, temporal, and geospatial. The results
reveal that in the UK, people express on Twitter more negative sentiments
towards the conflict, with a large number of positive tweets towards military and financial issues.
