Lukashev ran in the 2019 Ukrainian parliamentary election as the candidate of Opposition Platform — For Life (OPZZh) for People's Deputy of Ukraine in Ukraine's 113th electoral district. He was successfully elected with 33.66% of the vote, defeating 21 competitors including incumbent People's Deputy Vitalii Kurylo, who placed fourth with 7.92% of the vote.[2] During his election, Lukashev acquired attention after bags of sugar with his name on them were distributed in Luhansk Oblast by the Serhii Shakhov Foundation.[3]
In the Verkhovna Rada (Parliament of Ukraine), Lukashev joined the OPZZh parliamentary faction, and was chosen as first deputy chair of the Verkhovna Rada Committee on Education, Science, and Innovation.[4] Following the ban on OPZZh after the beginning of the 2022 Russian invasion of Ukraine, Lukashev joined Restoration of Ukraine, a successor organisation to OPZZh.[5] He also left his position as deputy chair of the Committee on Education, Science, and Innovation to join the Verkhovna Rada Committee on Finance, Taxation, and Customs Policy.[4]
Lukashev was one of the 47 People's Deputies to launch an appeal to the Constitutional Court of Ukraine against electronic financial declarations in August 2020, leading to the Constitutional Court to declare mandatory electronic financial declarations for People's Deputies to be unconstitutional.[6]
Prior to the Russian invasion of Ukraine, Lukashev was active in spreading Russian propaganda on Ukrainian news channels, on one occasion participating in a broadcast alongside Luhansk People's Republic politician Rodion Miroshnyk [ru]. Lukashev's appearance on Rada TV following the beginning of the invasion drew criticism from Ukrainian society, leading to the chief of Rada TV to promise to rectify mistakes.[7]
