Political parties in Turkey are crying foul after thousands of unlikely voters appeared on the electoral roll, BBC reported.

Among the oddities are many first-time voters over 100 years old - and one aged 165.

Opposition parties also said they had discovered more than 1,000 voters registered at a single apartment.

The discovery comes ahead of local elections in March, in which President Erdogan's AK Party may face its toughest political challenge in years.

Turkey has faced economic stagnation in recent months, and the value of its currency is significantly lower than it was a year ago. That has led to speculation that the dominant AKP could lose several key cities, including the capital, Ankara.

Opposition parties now say that voter lists are being manipulated.

The Republican People's Party (CHP) and the Peoples' Democratic Party (HDP) allege that the unusual voter records they have found are mostly areas where AKP lost by a small number of votes in previous elections.

CHP says there are more than 6,000 registered voters over 100 years old, many of which are supposedly older than the oldest documented living person, currently 116.

It includes 165-year-old Ayse Ekici, allegedly born in 1854, at the time of the Ottoman empire, and registered to vote for the first time his year, CHP said.

Another voter, known only as Zulfu, is supposedly 149. There is also Ayse, said to be 148 years old.

There are also widespread examples of suspiciously large numbers of people registered at a single address, opposition parties say.

In addition to the 1,000 people reported registered at a single apartment, there are many apparently registered at buildings that are empty, or at construction sites, or on the fifth floor of a four-storey building in one case in Istanbul.
