The deadlines for applying for a proxy or postal vote in the General Election have now passed. But an "emergency proxy vote" can still be applied for in certain circumstances. Details below, courtesy of the Electoral Commission site aboutmyvote.co.uk.
Apply to vote by proxy
The deadline to apply to vote by proxy in Great Britain was 5pm on Tuesday 28 April. However if, after this point, you become unable to go to the polling station for reasons relating to disability (including medical emergencies), occupation, service or employment, you can apply for an emergency proxy.
To do this you must be registered to vote individually, and submit an emergency proxy form up until 5pm on polling day.
If there isn't time for you to return a proxy voting application form by post you may be able to deliver it by hand or send a scan of the completed and signed form via email. To find the contact details for your local authority enter your postcode in the pink Your local area box. If you are concerned about your form arriving on time, contact your local authority for further advice.
Emergency Proxy for a Disability
If you have a medical emergency occurring after 5pm, 6 working days before the poll, you can apply to vote by emergency proxy (until 5pm on the day of the election).
Emergency Proxy for Occupation, Service or Employment
If you are unable to go to your polling station due to your occupation, service or employment, and you only become aware of that fact after 5pm, 6 working days before the poll (until 5pm on the day of the poll).
