Azwan Ali was among the first few voters who showed up outside the SK Klang Gate polling centre, where his brother Azmin Ali will also cast his ballot.
The two have an adversarial relationship, with Azwan having contested against Azmin for the Bukit Antarabangsa state seat in 2018.
Azmin had moved from Bukit Antarabangsa to Hulu Kelang which is seen as a safer seat for him after losing the Gombak parliament seat last year.
