Labour has highlighted NHS figures which it claims show a decline of GP services under the Conservatives.
The figures show that in October there were six million GP appointments – out of 31 million – for which patients had a wait of more than two weeks.
Labour said it was "yet more damning evidence of the crisis our NHS is in after a decade of Tory cuts".
The Tories responded by highlighting their plans to deliver 50 million more GP appointments by 2024-25 if elected.
The figures, from NHS Digital, do not distinguish between those patients who were content to wait for a more routine meeting at their local surgery and those who wanted a more immediate appointment and could not get one.
The latest data from NHS Digital show that 2.45 million patients waited between 15 and 21 days in October to see a GP or other practice clinician, which was 8.3% of the total number of appointments, compared with 8% in October 2018.
Another 1.69 million waited between 22 and 28 days for a GP appointment while 1.66 million waited more than 28 days.
In both cases there was an increase in the percentage of patients affected compared to October last year.
The overall number of appointments increased to 30.8 million in October 2019 from 29.7 million in the same month the year before.
Shadow health secretary Jonathan Ashworth said: "More families are struggling to get a GP appointment after the Tories have allowed the numbers of family's doctors in our communities to fall."
He said Labour had a £40bn rescue plan to invest in general practice which would see more doctors recruited and provide millions more GP appointments.
Labour also quoted new figures on the GP workforce in England which show that the number of fully qualified doctors in general practice had fallen by more than 1,600 since September 2015 to just under 27,000 in September this year.
The Conservative government had promised in 2015 to add 5,000 GPs by 2020.
However, the Tories refer to a different measure which includes qualified doctors training to be GPs – this group has increased by about 400 since September 2015.
Health Secretary Matt Hancock said: "It's great news that we've seen an increase in the number of GPsRead More – Source
