Labour's biggest union donor Sharon Graham launches an attack on Rachel Reeves

Labour's biggest union donor has launched an attack on Rachel Reeves, saying voters are no longer able to trust the party as her Budget broke promises to workers.Unite boss Sharon Graham criticised the watering-down of the Employment Rights Bill and the decision to hit 'ordinary' people with stealth taxes. On Wednesday, the Chancellor announced she would be raising taxes to pay for an increase to the welfare bill, including the removal of the two-child benefit cap.And she has since been accused of 'lying' to the public in the run-up to the Budget over the state of the country's finances.In an extraordinary move, the Office for Budget Responsibility revealed that the Chancellor was told months ago that there was no £20billion black hole.
