The “bottom line” for the Tory backbenchers is understood to be a ban on all Scottish MPs having any say over administration over laws and decisions that solely affect England. The would create a “degree of symmetry”, with days set aside in the House of Commons purely for English legislation. Effectively English MPs would be “double hatting” – sitting some of the time as an English MP and some of the time as a British MP. This would mean that a new legislature just for English MPs would not be required.
