On 18th September Scotland will have a referendum on Scottish Independence. The decision will have a lasting impact, not just on Scotland, but on the whole of the UK. I joined Ed Miliband, Leader of the Labour Party; Johann Lamont, Leader of the Scottish Labour Party; Anas Sarwar, Deputy Leader of the Scottish Labour Party; Margaret Curran, Shadow Secretary of State for Scotland; and Labour MPs from across the country to show our support for Scotland to remain part of the UK as the #indyrefexpress bus made its way to Westminster.
