Labour MP for Cannock Chase, Dr Tony Wright, is being treated for leukaemia, it has emerged.
Tony Wright has been had cancer for several years
The 56-year-old has had the condition for several years and is having chemotherapy, a Labour Party spokeswoman confirmed.
Dr Wright, a father-of-three, said he was determined to continue both his constituency and parliamentary work.
He was elected to the old constituency of Cannock and Burntwood in 1992, and became the Cannock Chase MP in 1997.
'Touched by cancer'
Sue Woodward, Dr Wright's constituency assistant, said: "Tony has had this condition for several years, as some people know, but as he is currently having chemotherapy for it, we thought it right to make a statement about it.
"He is working normally and is as busy as ever in the constituency and at Westminster and just wants to get on with his job."
Dr Wright said: "I am grateful to all those people who have given me their best wishes.
"There is hardly a family in the area which has not been touched by cancer in one way or another at some time, so my experience is no exception.
"I am glad to say that the NHS is doing me proud, and I am working as normal.
"God and the electorate willing, I am hoping to continue to do so for quite a few years to come."
Before entering parliament, Dr Wright, a London School of Economics and Oxford graduate, was a politics lecturer at the University of Birmingham.
As well as chairing the Public Administration Select Committee, Dr Wright chairs a cross-party group of MPs interested in constitutional affairs and citizenship issues.
He was parliamentary private secretary to the lord chancellor from 1997 to 1998 and has written a number of books on politics.
