Ahead of the 2014 general election, the Election Commission renumbered the seat for Chittagong-16 (Sandwip) to Chittagong-3, bumping up by one the suffix of the former constituency of that name and higher numbered constituencies in the district. Thus Chittagong-14 covers the area previously covered by Chittagong-13. Previously Chittagong-14 encompassed Lohagara and all but seven union parishads of Satkania: Bazalia, Dharmapur, Kaliais, Keochia, Khagaria, Puranagar, and Sadaha.[5][2][6]
Nazrul Islam Chowdhury was elected unopposed in the 2014 general election after opposition parties withdrew their candidacies in a boycott of the election. Nazrul Islam Chowdhury defeated Colonel Oli Ahmed with a margin of 1,68,000 votes in the 2018 general election[11]
