Nick Clegg proposes such a plan. Now the flippant answer to this is simple "remove the Lib Dems, then". But this doesn't answer the question. And besides, there never will be 150 Lib Dem MPs to remove.
On a serious note, Clegg's justification doesn't work. He wants to remove 150 MPs from the Commons - taking it to around 500 - to save money. Well, primarily to save political parties from having to raise money from big donors. Let's have a little pop quiz:
So why do political parties raise money?So Clegg's idea that fewer MPs equal less need for party fund-raising just doesn't make sense... especially since he also wants more state money to go to political parties. Which would eat up the £30m savings he said would be generated by cutting the number of MPs. There is, of course, another way of saving money - cutting MPs salaries or expense allowances.
a) To pay MPs
b) To run the rest of the party
c) So they can swan off on holiday
The idea of cutting the number of MPs also raises other questions - such as the potential impact on democracy. Is fewer MPs a goof thing? Not in and of itself. If anything, actually, more of a bad thing as MPs become more and more distant from their constituents. Any reduction in the numebr of MPs would have to be matched in devolution of powers to local councils, or as part of a proper devolution system - equal English, Scottish, and Welsh parliaments.
The plan to reduce the number of MPs sounds good in a press release or a speech, but in reality it isn't much cop. The downsides of the loss of representatives simply isn't worth the tiny amount of money that is [supposedly] to be saved.
