1974 Britonian referendum on joining the European Economic Community

The 1974 Britonian referendum on joining the European Economic Community (EEC), commonly referred to as the EEC referendum, took place on 7 April 1974 in the State of Britonia to ask the electorate whether the country should begin accession talks with the EEC. It was organised and facilitated through the European Community Referendum Act 1974 and was part of the Democratic Coalition agreement between KDK, PSB, PKB and PAP. The referendum resulted in 57.57% of the votes cast being in favour of beginning the talks. The referendum was legally binding, as stipulated in the Act, and required the government elected in the 1974 Britonian general election to begin accession talks with sincere intent to join the EEC as fast as possible.

The referendum was held alongside the 1974 election, and was the second referendum held in post-Seżer Britonia, being preceded by the constitutional referendum in April 1973, which provided the constitutional framework for a binding referendum and for holding the first multi-party general election since the 1930s.

The topic of Britonia's potential membership in the EEC had been one of the most divisive issues in the Democratic Coalition, with the majority of PSB and PKB members and their associates opposing membership, whereas the majority of PAP and KDK members supported it (albeit reluctantly in the latter case). There were examples of PSB and KDK members on the opposite sides, but they were a minority of their respective parties.

It was eventually agreed that the issue should be put to the public, and following the new electoral laws included in the 1973 constitution, campaign advertising was limited to the dissemination of leaflets detailing arguments for a particular side, political broadcasts on television (usually two per party/campaign per election/referendum), and hustings events/debates. All campaign ads, broadcasts and leaflets in Britonia must be vetted by the Electoral Commission, and in the event of severe electoral misconduct the Commission has the power to request the president calls fresh elections/referenda - this must be granted unless the president thinks the Commission has become partisan, in which case it must be taken to the Supreme Court.
