Narrative:

On vectors north of airport to join zzzzz arrival at zzzzz intersection; due to weather. During descent out of approx. 20;000 ft.; ECAM F/ctrl elac 1 fault appeared. I remained flying pilot; first officer ran ECAM per SOP; and [our] follow up. Elac 1 would not reset; and the resulting loss was also one of two available servo jacks in each aileron. After discussion with first officer regarding the resultant flight control malfunction; we decided to [request priority handling] as it was the conservative thing to do. ZZZ was the closest airport so continued there. First officer notified ATC and company of malfunction; and I briefed the flight attendants of the situation and to treat as precautionary landing. Briefed the passengers of the situation and assured them that all systems were operating normally. Also told them there would be safety vehicles near the aircraft after landing and nothing to be alarmed about. After vectoring around the weather in the area; we accepted visual approach to runway xx. Landed without incident and taxied to gate.weather was about the only factor having any effect on the whole situation. Was handled calmly and per SOP. There was a previous write up in logbook for same ECAM.
