Central Suffolk MP Dr Dan Poulter is set to return to Westminster next week after being away for two months.

Dr Poulter has been unwell and receiving medical advice for the last two months after he was referred to Conservative Party disciplinary committee after allegations were made about his conduct.

He had hoped the committee – which has also been investigating allegations against other MPs – would have completed its investigation before parliament broke up for the Christmas and New Year holiday.

However earlier investigations – including that into former First Secretary of State Damien Green – took longer to complete than expected and Dr Poulter’s case was still waiting to be investigated when the parliamentary break began.

Although he has not been working in parliament, Dr Poulter is in regular contact with his staff and giving them instructions about dealing with constituency matters.

He is hoping to return to the House on Tuesday. He will be returning to work gently at first, but hopes to soon be back to normal.

A spokeswoman for him said: “Dr Poulter looks forward to making a vigorous return to Westminster early in the New Year.”

Meanwhile the Suffolk People’s Assembly has written to him asking him to support a Labour parliamentary motion about the future of the NHS.

A letter from the group said: “We are sorry to hear you’ve been unwell. However, as a doctor and former Parliamentary Under Secretary of State at the Department of Health, we think you should be responding to the current situation in the NHS.

“We would also like to know if you are prepared to sign Early Day Motion 660(about the future management of the NHS).”

The spokeswoman said: “Dr Poulter is grateful to the Suffolk Peoples Assembly for their correspondence and for their kind wishes.

“He is happy to assure them that the needs of his constituents remain paramount and he has ensured that they continue to be effectively represented. Dr Poulter’s Constituency office remains fully in touch with constituents with all matters being dealt with speedily in writing. Dr Poulter is also fully informed on all matters at Westminster.

“As a general rule, Dr Poulter does not sign Early Day Motions. However, he has already raised the concerns put to him today by the Suffolk People’s Assembly directly with the Health Secretary.

“As a practising NHS doctor, Dr Poulter has always taken the keenest possible interest in the provision of high quality local health services for his constituents and the people of Suffolk.

“He is fully aware of how difficult and frustrating it is for those patients, both in the constituency and nationally, whose operations have been postponed. Like the Prime Minister and the Secretary of State of State for Health he offers them his heartfelt apologies.”
