Lord Falconer, the former Secretary of State for Constitutional Affairs, has stated that he believes that an English Parliament would "dwarf all other institutions." Peter Hain, who campaigned for a Welsh Assembly, warned creating an English parliament or trying to stop Scottish and Welsh MPs from voting on England-only matters would break up the Union. Chuka Umunna suggested in July 2015 that the Labour Party should support the creation of a separate English parliament, as part of a federal United Kingdom.
