The Benelux Parliament (officially known as the Benelux Interparliamentary Assembly) is one of the institutions of the Benelux economic union. The Parliament was established by an agreement signed by Belgium, the Netherlands and Luxembourg on 5 November 1955, which means it had already existed for three years when the Benelux Union was signed on 3 February 1958. The Benelux Parliament provides the governments with advice on economic and cross-frontier cooperation. Its recommendations may also concern other matters if common interests or current events so dictate. The parliament also keeps the three governments informed about the opinions that move in the parliamentary assemblies from which its members originate.
