The bill will be heard for the first time in debate from 3.30-10pm, with votes to follow, and follows the recommendations of the Smith Commission, which was set up after the independence referendum. It gives Holyrood control over income tax rates and bands, a half share in VAT revenues and a greater say over welfare powers in Scotland.
