No party, coalition or independent candidates' committee registered for the 25 October 2026 presidential election sent a representative to a public review of the source code for the vote-counting software. The Central Election Commission (CEC) and Information Services organised the review.

It took place in the National Assembly. It covered the code for the systems that the regional election commissions and the CEC will use to process voting data on computers.

Earlier the same day, Information Services showed the system itself in public. Each registered political force and independent candidates' committee could send one authorised representative to both events. Registered candidates, observers and media representatives could also attend.

Information Services experts were in the hall. They explained the system and answered questions, each on their own part: showing results online, the calculations and the work with the machines.

Alexander Stanev, head of the project for computer processing of election results, said the morning event covered the software system and its separate processes. He said the code review was meant for representatives of the parties and of the candidates they back, so they could look at the source code.

A similar review was held six months ago, Stanev said. Interest was much higher then, and representatives sat down and went through different parts of the systems.

The systems look little different. The only change a user sees is that data from the machines used to be read and published online for comparison. Now it is used directly to work out the result.
