Great article here by Michael Dobbs who is introducing the Referendum Bill in the Lords.
Michael describes the manouverings of those Labour and Lib/Dem Peers and MPs who want to stop the public having a say on Britain's membership of the EU, but who want to kill the referendum bill behind closed doors so that, quote,
“What they don’t want to do – I don’t think anyone wants to do – is have their fingerprints on the dagger that kills it.”
He compares these tactics with those of his fictional villain Francis Urquart (F.U.) from "House of Cards."
