|Voters queuing for a famous election in 1994 (S Africa)|
Many people regret not getting a postal vote (you don't have to give a reason). Sometimes holidays, bad weather, illness or a busy work schedule intervenes. It is very easy to get a postal vote. Just follow the instructions here. The link also gives information about getting a proxy vote if you want someone you trust to vote for you.
With the local election on Thursday 3rd May, the postal ballot papers get sent to you in the post on Monday 23rd or Tuesday 24th April.
