Liane & Abby, Special thanks to you for your advice and information, thanks to everybody who commented.
Wife got the certificate today at the Good Shepherd, she went straight there after her visit to the Embassy and they entertained her during the afternoon.
She had to call me at 6am UK time this morning to ask my mothers maiden name !!!! and my works phone number! Seems an odd question for them to ask but still all done now.
Thanks again
