On 15 September 2015, the House of Commons voted to decrease Tax Credit thresholds, a law that came into effect on 6 April 2016. Opponents claimed that it would harm those on low incomes. Simon Hopkins, Chief Executive of charity Turn2us commented "Today's vote in the House of Commons will mean one thing for many of the poorest working families in the UK; they are going to get poorer. Tax credits are a vital source of income for those on a low wage and for many they make up a substantial portion of their monthly income.
