Failure to devolve power to England could threaten the future of the UK, two senior MPs say.
Monmouth Tory MP David Davies, chair of the Welsh Affairs select committee, said English taxpayers may "wake up" to the unfairness of the situation.
Labour MP Graham Allen, whose select committee oversees constitutional reform, fears it could boost UKIP.
Their warnings come as the UK government considers giving Wales major borrowing and taxation powers.
