The article presents the main parties (i.e. the Conservative Party, Labor Party, Liberal Democrats and Scottish National Party) results of the 2019 UK general election as well as an analysis of the most important issues (i.e. correct identification of voters’ expectations, simplicity and clarity of the messages, leaders’ personalities) which determined each party success or loss. The author proves that since Brexit was the primary focus of voters, the level of support for particular parties remained dependent on the solutions presented in this issue. This basis explains why the Conservatives in the whole UK and the SNP in Scotland won (and the Labor Party and the Liberal Democrats lost) the battle of Brexit.
