If you are a registered voter but do not vote who has your vote?

No one has your vote. Every registered voter is entitled to a single vote; if you choose not to cast your vote or are unable to do so, then your vote simply goes unused. All unused ballot papers are counted and tallied under the supervision of the returning officers as non-issued ballot papers, in order to prevent the possibility of them being used electoral fraud, and are incinerated after being available for inspection for one calendar year.
