You should keep the nomination papers secure. By law, you must allow public inspection, and copies to be taken, of the nomination papers and consent to nomination during office hours on any working day from the close of nominations up to and including the day before polling day.1
Any person may inspect and take copies of or extracts from the nomination forms or the consent to nomination forms.
After that point, the nomination papers are not open to public inspection.
You should securely store them for one year after the election, after which you should destroy them unless ordered not to by a Court.
Objections to nomination forms
There is no right of objection to a nomination at either the election for the Mayor of London or the election of London-wide Assembly Members.
