DH just asked...

[frakyouveryverymuch]

Assuming the wedding tomorrow goes off smoothly and Catherine produces an heir(ess) and William accedes to the throne then dies before said heir(ess) reaches his/her majority....

Who becomes Regent? Her or Harry?

Er...I think the Privy Council pick someone suitable. It doesn't have to be the next in line to the throne. But Harry would obviously be a possibility!

Someone hopefully will come along and confirm this or give the right answer!

Harry ?
