The Conservative Party is not honouring the commitment to Lords reform and, as a result, part of our contract has now been broken. Clearly I cannot permit a situation where Conservative rebels can pick and choose the parts of the contract they like, while Liberal Democrat MPs are bound to the entire agreement.
