Is Euroscepticism Contagious?

How Mainstream Parties React to Eurosceptic Challengers in Belgian Parliaments

Abstract

Euroscepticism has long been absent among Belgian political parties. However, since the start of the century, some Eurosceptic challengers have risen. This article examines the effect of Eurosceptic competition on the salience other parties give to the EU and on the positions these parties take in parliament. Using a sample of plenary debates in the federal and regional parliaments, we track each party’s evolution from 2000 until 2019. Our findings both contradict and qualify existing theories and findings on Eurosceptic competition. When facing Eurosceptic challengers, all parties raise salience fairly equally, but government and peripheral parties adopted (soft) Euroscepticism more often than other parties.
