First class stamp price rises to £1.80 as Royal Mail cites rising costs

First class stamp prices rose to £1.80, a 10p increase. Second class stamps also increased by 4p to 91p. This price hike occurs despite Royal Mail's repeated failures to meet delivery targets and growing concerns about service performance. Stamps bought before the increase remain valid. The cost of first class stamps has more than doubled in six years. Royal Mail cited rising delivery costs and declining letter volumes for the change.
