Young voters were a key factor in the election of Prime Minister Kyriakos Mitsotakis in 2019, after the country emerged from a decade-long financial crisis.

This time, their backing is less certain. The Greek economy remains subdued and the young are feeling the impact - leading to a widespread disaffection with politics.

Andrianii Kotrotsou is a young professional who likes to take a stroll and enjoy a coffee in the park after work. It's an escape from everyday life, social media, and constant adverts about Sunday's national elections - in which she's entitled to vote for a second time.

But she's not sure whether to use her vote at all.

‌"For me, these elections are completely different from the previous one, especially in terms of what I care about and what I'm looking for," said Kotrotsou. "I don't feel that any of the leaders or their parties have anything to offer me. They don't seem to understand us young people. That's why I'm considering not voting."

‌Some 500,000 young people in Greece are eligible to vote - more than eight percent of the population. Many are still angry over the deadly train crash in Tempi in February and are calling for changes to the structure of the state, and the political system.

Inflation and unemployment are also sources of frustration.

‌Recent polling shows one in three people between the ages of 17 and 30 are planning not to vote at all. It's prompted candidates to take to social media more, hoping to reel them in.

‌But young people feel it's counterproductive.

‌Most young people here seem to despise politics and politicians. Youth unemployment is close to 30 percent. The influence of those in power, and the parties they represent, is decreasing, with young people feeling ignored and voiceless. But the way they're expressing their frustration is changing.

In 2015, after the decade-long financial crisis, Greeks, especially young people, voted in large numbers for the previously little-known left-wing Syriza party. Now, many seem to be taking a different approach -- and not showing up at all.

"Most young people have realized that political parties don't have a plan about incorporating technology in their lives, such as Artificial Intelligence which is being incorporated at a very fast pace," said Giorgos Trapalis, Data Analyst. "This will reshape the working market and young people are aware of it. This lack of voting is not a punishment, it's rather young people calling for a helping hand."

Although most political parties have presented targeted plans, like raising the minimum wage and grants for the unemployed, the polls show young people are not convinced.

They represent a large part of society. By staying away from the ballot box, they could have a strong influence on Greece's political direction.
