A ORB poll of 2,000 people published on Friday by the Independent showed 55 percent of respondents believed Britain should leave the EU, while 45 percent favored staying in.
Another poll by Opinium for the Observer suggested 44 percent of Britons backed continued membership of the trade bloc, 42 percent were against it and 13 percent undecided.
British Prime Minister David Cameron warned in a Sunday interview with the Observer that Brexit would have an impact on British health spending, referring to research by the Institute of Fiscal Studies and the National Institute for Economic and Social Policy. The research showed Brexit would create a black hole of up to 40 billion pounds in the U.K. public finances by 2020.
The British pound traded at $1.4184 on Monday morning Asia time, compared with levels between $1.4500 and $1.4600 in the previous week.
