Lindsay Roy MP confirms he has Parkinson's as condition deteriorates
The Labour MP is unable to travel to Westminster while he undergoes treatment and will stand down.
Labour MP Lindsay Roy has confirmed he is suffering from Parkinson's Disease.
The Glenrothes and Central Fife politician has already signalled his intention to stand down at the next election.
The 66-year-old has been prompted to reveal details of his battle with the disease as he cannot travel to Westminster while he is receiving treatment.
A spokeswoman said he would continue to work full-time from his constituency office in Glenrothes.
Several politicians have paid tribute to Mr Roy's contribution to politics and education.
The former headteacher is particularly known for his dedication to local matters, often opening his Glenrothes office from 6am as well as at weekends so working constituents could speak to him.
Angus Robertson, the Westminster SNP leader and MP for Moray, tweeted: "Wishing Glenrothes and Central Fife Labour MP Lindsay Roy well after he confirmed he's battling Parkinson's disease."
Labour's Mid Scotland and Fife MSP Jayne Baxter said: "Lindsay Roy MP was a (very young) teacher when I was a (relatively old) pupil at Queen Anne High School.
"I still know him today, 40 years on, as a colleague and friend. I was sad when he told me of his illness but I know he will not be overwhelmed by it.
"I wish him well and would like to thank him for his contribution to the lives of thousands of young Fifers as a headteacher and of course to the lives of his constituents in Glenrothes."
The next general election will be held in 100 days and Labour has confirmed that Mr Roy's successor has already been chosen.
Melanie Ward is a former president of NUS Scotland and also lives in Glenrothes.
A spokeswoman for Mr Roy said: "Lindsay actually handed his notice in in November 2013. His illness had nothing to do with his standing down. He wanted to do it so far in advance so that he could shadow the incoming candidate for a year.
"He has always been very active in the community and he runs a very busy office but sadly his condition has deteriorated quite rapidly."
Mr Roy told The Courier: "The effects of the illness are such that I am currently unable to travel to London but plan to return there soon.
"In the meantime I will continue to work full time locally on behalf of constituents.
"It has been an honour and a privilege to represent the people of Glenrothes and central Fife ever since I was elected in 2008 and I can assure them that I will continue to work hard on their behalf until I retire at the general election in May."
Mr Roy secured the Glenrothes seat for Labour in a by-election following the death of MP John MacDougall.
This success was followed by an overwhelming victory in the 2010 general election, when he more than doubled his majority to more than 16,000.
Mr Roy was rector at Inverkeithing High School for 19 years and had a short spell at the helm of Kirkcaldy High before entering politics.
He was awarded the CBE for services to education in Scotland in 2004.
Parkinson's disease, which is incurable, affects one in every 500 people in the UK. Symptoms can include tremors, muscle rigidity and slowness of movement, which can be treated with drugs and therapy.
