So the prime way that David Cameron sees as giving greater power to the voters in England in a small "f" federal UK is English votes for English laws in Westminster. He is therefore short changing the people of England do not be fooled by him.
In Scotland the Scottish MSPs can vote on Scottish laws in a chamber that is elected via a proportional voting system. Admittedly for the last 3 and a bit years that has been an SNP majority that the majority of voters didn't want but has in the past led to consensus politics.
In Wales the AMs can vote on Welsh laws also in a chamber that is elected via a proportional system, at times Labour have run the administration on its own but it has also often led to consensus politics.
In Northern Ireland while the MLAs are elected on a wholly constituency basis, it is a proportional system so unlike Scotland and Wales it does not have regional top up lists to ensure that people's views are represented as this is done in the six member seats.
If only the 533 English MPs could vote on whatever ends up being deemed to be an English only matter (something that there is actually very little of due to funding impacts for the devolved nations), it would mean that 39.6% of the electorate would end up with 55.9% of the MPs making their decisions. With boundary changes that were brought in since 2010 many of the 92 gains that the Conservatives made are supposedly harder to take away from them. But Labour with 28.1% of the vote and Lib Dems with 24.2% in England last time would have 35.8% and 8.1% of the MPs making such decisions respectively.
It is not proportionate as the other three member states have.
It is as Nick Clegg so rightly pointed out really a case of Tory votes for English laws.
What David Cameron is actually proposing is selling the people of England short and not giving them a true reflection of what the rest of the UK has experienced since devolution. He doesn't get what it is that makes the powers that true devolution can bring, he is seeing it as a way of regaining some control in some part of the UK, but to do so absolutely as only when the SNP had a majority from 2007-11 did they have any real say in any of the devolved powers.
