Stanley was shouting full-throated slogans in the Well during Zero Hour seeking justice to Tamils in Sri Lanka as her colleagues as well members from arch rival AIADMK waved photographs of slain LTTE chief Prabhakaran's son killed by Sri Lankan forces.
Renuka Chowdhary, who was in the Chair, immediately adjourned the House till 2 PM and called in doctors to attend to Stanley, who lay unconscious on the floor.
The DMK member was immediately rushed to Safdarjung Hospital after two doctors attended to her in the House. A stretcher as well as a wheel chair was also brought in but Stanley preferred to walk with support of members including party leader in the House Tiruchi Siva.
Members from the ruling party including Ambika Soni, D Purandeshwari, Rajeev Shukla as well as those from AIADMK and other parties rushed to help the sick member.
Earlier, the House was adjourned till noon over the issue of Sri Lankan Tamils and Union Minister Beni Prasad Verma's remarks against SP chief Mulayam Singh Yadav.
All the while, SP members led by Naresh Agarwal sought Verma's dismissal.
In the meantime, Stanley fell unconscious triggering a chaotic situation.
After adjourning the House, Chowdhary left her seat and went to the Well to ask Stanley as to how she was feeling. "Did you have your breakfast, madam?" she asked.
Chowdhary then asked members to leave and make way for Stanley while asking for doctors to attend to her. Stanley rested in a seat for a while before being taken to hospital.
