Hi Elizabeth, I would be very careful about this as it does seem that you have committed Bigamy (albeit unknowingly) unless you are a Muslim. I have posted a link here:

http://en.wikipedia.org/wiki/Bigamy

The three countries concerned, Hong Kong, Philippines and the UK, all say it is illegal to remarry whilst still legally married, so be very careful how you go ahead with this. I would suggest that you remarry and then go ahead with your plans as newlyweds.

I don't want to sound alarmist, but please look into the link I have sent you. Hopefully this will help you, not maybe with your visa application, but with the status of your marriage. As I said, if you are Muslim, then it seems you will NOT have broken UK Marriage laws. Goodluck!
