The letter also tells GPs that they should ‘not feel under pressure to form working arrangements at this stage.’

Mr Lansley also writes that his proposals are not about ‘overburdening you with paperwork or involving you in the minutiae of administration.’
He reemphasises that consortia will determine their own size and structure, with central guidance kept to a minimum.
‘Only essential duties’ will be set out as statutory duties, he writes.
Mr Lansley uses much of the letter to calm the profession as it prepares to take on full commissioning responsibility by 2013. He writes that GP consortia's duties will be clarified after the consultation and the health bill has gone through parliament.
He asks GPs to start considering who they would like to work with, what services they feel are appropriate to commission themselves and where they might want support.
