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?

[Rhinestone]

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 ?
