British PM Cameron faces revolt from unelected House of Lords over tax credit cut plans

With a majority in the British parliament's lower chamber, the House of Commons, Prime Minister David Cameron should have no problem implementing his policies.

But Cameron is facing rebellion from the unelected House of Lords — and some of his own Conservative lawmakers — over cuts to tax credits for parents and people in low-income jobs.

The House of Lords, Parliament's unelected upper chamber, is scheduled to vote Monday on whether to take the rare step of defying the House of Commons by striking down the cuts.

The Labour opposition is calling for a U-turn, and some Conservative lawmakers also oppose the move, which they say undermines the center-right party's claim to champion working people.

Critics say as many as 3 million people will be worse off under the changes.
