The GPC said GPs in Northern Ireland had been 'cut adrift' from the rest of the UK by their government's refusal to sign up to the 2011/12 GMS contract, which was announced last week.
Explaining the delay, Mr McGimpsey said: 'My budget was not given to me until Thursday evening past (10 March).'
GPC chairman Dr Laurence Buckman said he was ‘appalled’ by the delay.
Dr Buckman said it was the first time the UK contract had been announced without the support of all four countries.
He claimed the delay was down to ‘ministers from different political parties trying to demonstrate their political potency’.
