The first page of the manifesto document will commit a new Labour government to a “budget responsibility lock”, guaranteeing that every policy is fully costed and will not require any additional borrowing. However - unlike the Conservatives and Liberal Democrats who launch their manifestos later this week - it offers no timetable for clearing the deficit, saying only that it will get national debt falling and a surplus on the current budget “as soon as possible in the next parliament”.
