Mrs Bercow said the person publishing her details was "not very nice"
Commons Speaker's wife Sally Bercow has complained about being featured on a website monitoring MPs' movements.
Mrs Bercow writes on her page of the Twitter social networking site: "I am not an MP. I just live here. So stop reporting my movements."
The owner of the EyeSpyMP page replies: "You Twitter your movements far more than we do. You love the limelight."
EyeSpyMP has reported sightings of Mrs Bercow drinking coffee and playing with her daughter.
On her Twitter page, Ms Bercow, who is standing for Labour in Westminster in May's local elections, warns the anonymous founder of EyeSpyMP: "I am going out now. To do school run. I am not an MP. I just live here. So stop reporting my movements. Thank you. :) "
'Taken with scaffolder'
When rebuffed, she adds: "You are not being v. nice. You are clearly a bunch of Tories."
Mrs Bercow, whose husband John was a Conservative MP before being elected Speaker last year, is a frequent Twitter user.
Her page tells of her political views and daily life inside and outside the Speaker's Westminster Palace apartment.
One recent entry reads: "Friend popped round. She is very taken with a scaffolder working on Parliament's roof. I left her to it & went to meeting... will get update."
Another reads: "Lunchtime. The kids will only eat food they've seen advertised on TV. Which is limiting."
EyeSpyMP, formerly known as Parliament Spy, restarted last month, having previously been removed from Twitter.
