A medical incident occurred during a campaign rally in Portugal when the country's right-wing nationalist leader, André Ventura, suddenly collapsed mid-speech.

The event took place after he consumed water, at which point he froze and then grabbed at his chest and neck, exhibiting visible signs of distress.

Immediately following the incident, aides rushed to assist him.

The sudden collapse happened in front of a gathering of supporters who had attended the rally to hear Ventura's speech.

Details regarding the leader's current health status and the cause of the collapse are being assessed.
