Conservative MPs Rebel in Open Letter against House of Lords Reform [VIDEO]

Seventy rebel Conservative MPs have signed an open letter criticising plans to reform the House of Lords in a move that shows the scale of division in the coalition government over the proposal.

The letter, sent out to MPs across the country, calls for "full and unrestricted scrutiny" of the bill, which will be debated over the next two days.

MPs including Jacob Rees-Mogg, Nicholas Soames, Nadhim Zahawi, Zac Goldsmith and Nadine Dorries have signed the public pledge to oppose the Lords Bill. There are 70 names specified in the letter, which ends: "Further names omitted."

The letter reveals the scale of the expected backbench rebellion against the Liberal Democrat-led push for reform of the house which will almost halve its membership while making 80 percent of the house elected to non-renewable 15-year terms.

The letter states: "The Lords Bill is a measure of profound constitutional significance. Over time it will fundamentally change the institutions by which we as a nation are governed. It threatens to pile a constitutional crisis on top of an economic crisis."

Setting the reform naysayers' stall out the day before the Commons vote on the bill's timetable, the MPs echo Labour calls for a delay.

It adds: "What is now proposed will undermine the primacy of the Commons, with competing chambers which will lead to legislative gridlock.

"It will create hundreds of unaccountable new elected politicians at a time when we as a party are committed to reducing the cost of politics and it will produce a chamber which is less expert, less diverse and significantly more expensive than the present one."

If the government's timetable for the bill should fall on Tuesday, if would represent a major, perhaps fatal, blow against its progress. The Lib Dems have already threatened repercussions should it fail, with the party suggesting it could make a rebellion of its own against the Conservatives' proposed boundary changes.

The full letter was published by the Guido Fawkes blog.
