So taking that logic to its conclusion, then we would need roughly 53 parliamentary constituencies in Wales to enable the Richard Commission vision of having 80 members of the Assembly sitting in Cardiff Bay!
This would require a new Act of Parliament to enable this unlikely scenario to happen.
However, one would assume that any incoming Conservative Government, in changing the number of MPs across the UK, would also make legislative provision for changes to the Government of Wales Act to enable the regional list calculation to change accordingly i.e. this would allow for the reduction in the number of MPs whilst maintaining the current number of AMs, as has happened in Scotland.
Of course, if the reductions in MPs were to be made and the link maintained between Westminster and Cardiff Bay constituencies, this could mean that there would be 30 first past the post AMs elected and a further 30 from the regional lists.
I wonder what that would do to Labour's election prospects in any future Assembly election?
