The Home Office have previously published data on the numbers of non-human primates imported and used for scientific research in PQs 222873 (05 Feb 2015), 182703 (20 Jan 2014), 80687 (22 Nov 2011) and 76262 (25 October 2011). The numbers of non-human primates imported into the UK for scientific research were: 2,071 in 2010; 1,771 in 2011; and, 1,557 in 2012. This data was gathered from information supplied by project licence holders when requesting permission to import.
On 1 January 2013, the Animals (Scientific Procedures) Act 1986 was amended to transpose European Directive 2010/63/EU on the protection of animals used for scientific purposes. The amended legislation has no requirement to request prior permission to import non-human primates acquired from overseas breeding centres. Therefore, the Home Office does not hold the information requested for 2013 and 2014. The published Annual Statistics of Scientific Procedures on Living Animals in Great Britain provide information on the sources of non-human primates used in experimental procedures for 2013 and 2014.
