This thesis is conducted as a descriptive comparative case study with the aim to explore the utilisation of different forms of nationalist arguments for secession by the Scottish National Party in the Scottish Parliament and Plaid Cymru in the Welsh Assembly. Based on the application of nationalist theories from three different modernist scholars, statements made by each party are analysed from politico-ideological, economic, and socio-cultural perspectives.

The Scottish National Party and Plaid Cymru share both secession as the ultimate goal and perceptions of being in a subjugated position within the United Kingdom. However, the results of the qualitative textual content analyses show that the approach towards secession is fundamentally varied between the two parties. The Scottish National Party utilises predominantly economic arguments for independence whilst Plaid Cymru find themselves arguing for further devolution of powers together with attempts to differentiate themselves from the UK.

This study confirms a number of claims and ideas from previous research within the academic fields of nationalism and secessionism while simultaneously delivering findings on unexplored idiosyncrasies of nationalist discourses in Scotland and Wales. Subsequently, it is our aim to contribute to a deeper and more structured understanding regarding the content of nationalist arguments for secession.
