Rachel Reeves has declared her budget will slash living costs for millions including ending the two-child benefit limit and cutting energy bills, but taxes are set to soar by £26bn to plug a gaping shortfall in the public finances.

Major measures in the budget leaked early in a shock accidental release by the Office for Budget Responsibility (OBR), triggering an instant bond market reaction an hour before the chancellor was on her feet in the House of Commons.
