Starmer attacks Greens, saying vote for Labour rivals puts new workers’ rights at risk

PM also criticises business figures and opponents of changes, many of which come into force on Monday

• Workers, pensioners and children: all better off. Ignore the critics – we really are standing up for working people

Keir Starmer has used a series of new workers rights that come into force on Monday to attack the Green party, saying a vote for Labour’s rivals puts such progress on sick pay, parental leave and zero-hours contracts at risk.

The prime minister also took a swipe at business figures and opponents of what he described as the biggest strengthening of workers’ rights in a generation, dismissing “vested interests” who had warned against them.
