The price of a first class stamp for a letter weighing up to 100g will increase by 2p to 34p, while larger first class letters will rise by 4p to 48p.

The price of a standard second class stamp will go up by 1p to 24p, and by 3p to 40p for a larger second class letter.

Franked mail - both first and second class - will also go up by 2p, so a first class franked letter will cost 32p to post.

The announcement follows price rises in April this year, and the introduction of Pricing in Proportion (PiP) in August. See the full list of changes on the Royal Mail website.
