Referee's passport number

[Oyidoma]

Hi Guys,

Is it necessary for a British citizen acting as a referee for the citizenship application to include their passport number. In case this was not provided in the referee section, will that invalidate the application or give the Home Office reason to reject such application.

Thanks.

They should put it in. If they don't wish to, they can state 'provided on request'.

Thanks for the insight.
