A website to give TDs easier online access to what is going on in Leinster House ended up costing more than €1.88 million.
The digital parliament project had originally been budgeted at €1.78 million when it was given formal approval in the summer of 2020.
A business case for the project said it would make life easier for TDs to keep track of Dáil business, allow for publication in real-time, and for the sharing of content on social media.
