Half-way through my query and it all vanished into cyber-space, back to square-one.

Morning all,
My fiancée holds Canadian passport but is Filipina by birth, we are about to apply for visa through Ottawa. Does anyone know if, assuming we get the visa, it would be possible to visit Phili after getting visa but before coming to UK. In other words could my fiancée (clutching visa) go from Canada to Phili where I would meet her then we would both travel back to UK. Would the powers-that-be let us in. Bearing in mind that last Christmas when she was staying in UK with me we went to Spain and she encountered a 'kindly' official at passport control that was reluctant to let her back in to the UK!!
Regards to all,
Paul
p.s. the worry has started to build up for this afternoon – come on England!
