Do you know the price of a stamp?

A first-class stamp is to rise in price from 46p to 60p after the regulator lifted some controls on Royal Mail.

A second-class stamp will jump from 36p to 50p - some 5p below the top price allowed by Ofcom.

But do members of the public know how much a first-class stamp costs, and how do they feel about the price rise? BBC News has been finding out.
