Delft Open has been organised since 2017 by the TU Delft Debating Club. This English BP-style tournament is traditionally held around May in the Christelijk Lyceum in Delft.
Delft Open was held for the first time in 2017 and was also the first tournament that was organised by the TU Delft Debating Club. In 2017, the finals were held in Museum Prinsenhof. In 2020, the tournament was delayed from May to June due to the Coronavirus pandemic. Additionally, the debates were held online using Discord. Due to reduced organisation costs, the reg fees were lower in this year and a prize of 100 euros was awarded to the winning team.
