National Insurance number
The National Insurance number is used as a reference number in the Pay As You Earn system, and also by the self-employed. It is also used in applications for Individual Savings Accounts (ISAs), to check that an individual has opened only one ISA in a tax year.
Socialist Students
Socialist Students is a socialist organisation with branches in universities, further education colleges and sixth form colleges in the United Kingdom. Socialist Students was established in the late 1990s by members of the Socialist Party (SP) who had built support for the Save Free Education Campaign amongst students in the battle over the introduction of fees when the Labour Party under Tony Blair was elected in 1997.
