Prime Minister Theresa May has told the House of Commons that the United Kingdom will never give in to terrorism
Speaking to a packed House of Commons Chamber, the Prime Minister said: "Yesterday an act of terrorism tried to silence our democracy. But today we meet as normal."
The attacker's identity is known to the police and MI5, she said, and would be made public when possible.
He is British born - and "some years ago" was investigated by MI5. But he was "a peripheral figure", Mrs May said.
It follows Wednesday's terror attack in which four people, including the attacker, died.
Victims included police officer Pc Keith Palmer, a 48-year-old husband and father with 15 years of police service; a woman in her mid 40s, and a man in his mid 50s.
Aysha Frade was the first member of the public to be identified as a victim, with her principal at DLD College London describing her as "highly regarded and loved".
Seven people are in a critical condition, and 29 have been treated in hospital
The attacker, armed with two large knives, jumped out of the car after smashing it into the railings encircling the Palace of Westminster, fatally stabbing Pc Palmer as he entered the grounds. He was shot dead moments later by another officer.
A group of French schoolchildren were among those targeted on the bridge, with three injured
MPs went back to work, determined to return to business as usual in the wake of the terror attack on Parliament.
