These Regulations amend the Social Security (Invalid Care Allowance) Regulations 1976 (S.I. 1976/409), the Social Security (Attendance Allowance) Regulations 1991 (S.I. 1991/2740), the Social Security (Disability Living Allowance) Regulations 1991 (S.I. 1991/2890) and the Social Security (Personal Independence Payment) Regulations 2013 (S.I. 2013/377) to reflect that claimants to whom a relevant EU Regulation applies need only show a genuine and sufficient link to the United Kingdom and not the United Kingdom social security system.
