MPs get their first big debate later on proposals to transfer control of some taxes, including part of income tax, to the Welsh Government. Over the course of two sessions, Welsh MPs will discuss the recommendations of the Silk Commission which reported before Christmas.
The Commission recommended that Welsh ministers should be responsible for raising some of the money it spends through a range of taxes. It also said that the Welsh Government should have the power to vary income tax here in Wales.
The proposals will be discussed in detail for the first time in a meeting of the Welsh Grand committee in which all MPs from Wales take part along with a handful of members from other constituencies.
