William Hague tried to draw Labour further into the English votes debate as he accused them of "betraying" voters as he set out the Conservative blueprint for delivering "English votes for English laws."
However the proposals still face a tough battle with some in the Conservative party who believe the plans are too weak and would make the situation worse by providing nationalist MPs with a "battering ram against the Union".
Under the Tory manifesto proposals - which Mr Hague is seeking to put to a Commons vote before May's general election - policies affecting England alone would be scrutinised by a panel made up only of MPs representing English seats.
A "grand committee" of all English MPs would then have to approve the legislation. Welsh MPs would be included on matters not devolved to the Cardiff Assembly.
A large section of Tory backbenchers are angry that the final - Third Reading - vote on Bills would still include MPs from the rest of the UK, in what they say is a watering down of David Cameron's promise to act.
The deupty leader of Ukip has slammed Conservative palns for English MPs to be given vetoes.
Paul Nuttall says the proposals panders to the culture of "back room stitch-ups."
We cannot have the tail wagging the dog.
It would create chaos where one group of MPs were being pitted against another. It would be cleaner and fairer for English only issues to be voted on by MPs in English constituencies.
It is likely that after the General Election there will be more SNP members of parliament sitting in Westminster whose concern will be Scotland and not what is best for England. In that situation these plans would add layers of process and confusion to legislating and lead to back room deals being made far away from the voters eyes.
Why are the Tories are climbing down for English only votes? Is there already a back room stitch-up?
MPs representing Scottish constituencies would be stripped of the power to "impose" income tax rate changes on the rest of the UK under a parliamentary shake-up planned by the Conservatives.
It would give an effective veto to MPs for seats in England - and Wales on some policies - over matters that are decided north of the border by the Scottish Parliament, but would still require a majority of all UK MPs to pass legislation.
Under the preferred option, only English MPs would consider the amending stages of legislation that relates only to England and have a veto via a procedure known as a legislative consent motion.
William Hague has described how English votes for English laws would work in the UK Parliament.
The former Foreign Secretary told Good Morning Britain that: "If we're proposing to change the level of health spending in England then that does have an affect on Scotland and that is for all MPs to vote on. But if we're voting on how to share out the health spending in England in the different parts of England that should require the agreement of the English MPs."
William Hague said Labour have "learnt nothing from their mistakes" as he helped launch a scathing attack on the party ahead of May's election.
"They are committed from the start to more wasteful spending, more borrowing and higher taxes," the Leader of the Commons said.
"It is in their DNA," Hague added.
British jihadists returning to the UK from Syria after becoming disillusioned with the extremists could be used to dissuade others from going to join the conflict, William Hague said.
The Leader of the Commons said authorities would be prepared to assist former-fighters, if satisfied as to their "good intentions".
His comments come amid reports that some Britons who left groups like Islamic State (IS) fear returning home in case they face arrest.
Speaking on BBC1's The Andrew Marr Show Mr Hague said:
Our top priority has to be the protection of the security of the people of this country, and that is why we will take action where we think people could be dangerous. But the Home Office and the police and the health service are also working together on what we can do to assist those people who come back with good intentions, but of course we have to be sure that they do have good intentions. We haven't had a lot of those people coming back yet and saying they want to be of assistance, but if they do well then of course the Government, the police, the National Health Service, will work with those people and help them to recover and to assist others.
No one political party has a "monopoly of wisdom" on the NHS, outgoing MP William Hague told Good Morning Britain.
The leader of the House of Commons said he thought the Conservative party had done "a very good job" on the NHS and insisted "we all care about the National Health Service".
Former Foreign Secretary William Hague will answer questions in the House of Commons in place of the Prime Minister tomorrow, a spokesperson in David Cameron's office confirmed.
