Election buffs could be in for a long night on Friday as they wait to find out the make-up of the next Northern Ireland Assembly.
The poll will see 90 MLAs elected to Stormont - five in each of Northern Ireland's 18 constituencies. The counting will take place in three centres in the region.
Elections to the Assembly use the single transferable vote (STV) system, a form of proportional representation involving choosing candidates in order of preference.
