E/C.12/GBR/CO/6 adequate housing, especially with regard to the criminalization of rough sleeping in the State party (art. 11). 52. The Committee urges the State party to take immediate measures, including by allocating appropriate funds to local authorities, to reduce the exceptionally high levels of homelessness, particularly in England and Northern Ireland, and to ensure adequate provision of reception facilities, including emergency shelters and hostels, as well as social rehabilitation centres. The Committee urges the State party to adopt all necessary measures to avoid the criminalization of rough sleeping in the State party and to develop appropriate policies and programmes to facilitate the social reintegration of homeless persons. In this respect, the Committee draws the attention of the State party to its general comment No. 4 (1991) on the right to adequate housing. Right to food 53. The Committee is concerned about the lack of adequate measures adopted by the State party to address the increasing levels of food insecurity, malnutrition, including obesity, and the lack of adequate measures to reduce the reliance on food banks. The Committee is also concerned about the lack of adequate measures adopted to increase the rates of breastfeeding (art. 12). 54. The Committee recommends that the State party develop a comprehensive national strategy for the protection and promotion of the right to adequate food in order to address food insecurity in all jurisdictions of the State party and to promote healthier diets. This should include policies in support of breastfeeding in accordance with the resolutions of the World Health Assembly, including breastfeeding breaks or breastfeeding facilities in educational institutions and workplaces. The Committee also recommends that the State party introduce higher taxes on junk foods and sugary drinks and consider adopting strict regulations on the marketing of such products, while ensuring improved access to healthy diets. The Committee refers the State party to its general comment No. 12 (1999) on the right to adequate food and the Voluntary Guidelines to support the progressive realization of the right to adequate food in the context of national food security adopted by the Food and Agriculture Organization of the United Nations as well as to the International Code of Marketing of Breast-milk Substitutes. Access to health 55. The Committee is concerned that refugees, asylum seekers and refused asylum seekers, as well as Roma, Gypsies and Travellers, continue to face discrimination in accessing health-care services. The Committee notes that the Immigration Act 2014 has further restricted access to health services by temporary migrants and undocumented migrants (art. 12). 56. The Committee recommends that the State party take steps to ensure that temporary migrants and undocumented migrants, asylum seekers, refused asylum seekers, refugees and Roma, Gypsies and Travellers have access to all necessary health-care services and reminds the State party that health facilities, goods and services should be accessible to everyone without discrimination, in line with article 12 of the Covenant. The Committee draws the State party’s attention to its general comment No. 14 (2000) on the right to the highest attainable standard of health. 10
