The national minimum wage will increase by 20p an hour to £6.70 from October, the government has announced. The changes will benefit more than 1.4 million workers. The hourly rate for younger workers will also rise, and for apprentices it will go up by 20% – or 57p – to £3.30 an hour. The rates were recommended by the Low Pay Commission but the government has gone further than the 7p an hour increase suggested for apprentices.
