More than half the people in the UK think the country should be part of the European Arrest Warrant.
The warrant requires EU countries to arrest and transfer a suspected criminal to the country which requested the warrant so that that person can be tried.
A poll byYouGov found that 56% of people thought that the UK should participate, while 18% were against.
Some 100 Tory MPs, however, are of different opinion over the warrant and are expected to vote against it. Many believe it will result in Britons being extradited on spurious grounds.
Prime Minister Cameron tried to assure everyone that the UK is able to reject such spurious demands, having already reformed the arrest warrant.
Scores of arrest warrant requests have already been rejected since the reforms were announced in July.
MPs will vote soon on the issue.
