As it appears my suggestion has some support, I will propose it as law in the form I believe best.

Edict 3.3: All settlements in the British Isles will be given to Scotland. The Seneschal must attempt to obtain an alliance with Scotland in return for these settlements. However, if the Seneshal determines that the Scots will not agree to an alliance, no matter how favorable the deal, the Seneshal shall give the provinces to Scotland for whatever deal benefits France the most.
