The Chancellor is expected to announce that he'll ask businesses their views on transferring power over stamp duty to Wales. The transfer is one of the recommendations of the Silk Commission but the UK Government's response to its report has been delayed until the autumn.
It's thought part of the reason for the delay is a difference of views within the coalition government about the effect on the housing market of devolving stamp duty. A written ministerial statement from the Chancellor later is expected to launch a consultation ahead of the full response to Silk.
