Van Dijk worked as a legislative assistant to PVV MEPS Lucas Hartong and Vicky Maeijer.[1] In April 2018, he became a temporary member of the House of Representatives to cover for Gabrielle Popken who had gone on maternity leave and remained in the House to replace Karen Gerbrands who was on leave until 2021.[2] In the 2023 general election, van Dijk was number 17 on the Party for Freedom list, and he assumed his place in the House of Representatives on 6 December 2023.[3] He has been focused on European affairs since.[4]
During a 2020 debate on immigration in the House of Representatives, Van Dijk used the word "omvolking" (or "demographic replacement") when referring to his opposition to European migration pact. The debate was temporarily stopped after Christian Union MP Joël Voordewind accused Van Dijk of "using a term from the Nazi era" to which Van Dijk described Voordewind's comment as "too much for words" and demanded that he withdraw the accusation.[5]
In 2021, Van Dijk objected to House of Representatives criticism of the Hungarian government of Viktor Orban. Bram van Ojik had referred to Orban's 'limiting of press freedom, starting antisemitic campaigns, and limiting juridicial power'. Van Dijk defended Orban, claiming him to be "a leader that chooses for his own people."[6]
