Speaking about the findings Kate Allen, director of Amnesty International UK, said:
The torture survey showed 15% of people in the UK, around three in 20, fear being tortured if they are detained by the authorities - while 86% agreed clear rules against torture were needed.
More people in Britain believe torture can be justified than in Russia - thanks to popular TV shows such as 24, Homeland and Spooks, a new poll conducted by Amnesty International has said.
According to the poll, 29% in the UK think torture is sometimes necessary and acceptable to protect the public, compared to 25% in Russia.
One scene in popular TV show 24 shows a man tortured in the opening scene of the second episode. He is electrocuted by a machine that monitors his saline levels.
The research is published as Amnesty launched a new Stop Torture campaign and revealed that 27 different types of torture were reported during 2013/14, in at least 79 countries so far.
The first teaser for the third season of US espionage drama Homeland has been released ahead of the show's return to TV screens in the US on September 29.
It features various sound bites of conversations including those of lead protagonist Nick Brody which serve to add to the suspense but give very little away.
