A group of six pensioners who had planned to deliver a petition Charnwood MP Stephen Dorrell found themselves facing police and being accused of trespassing.
Bill Hill, 79, from Birstall, and five friends, had gone to Mr Dorrell's surgery in Melton Road on Friday to hand over a 2,286 signature petition asking the politician to resign.
Their campaign is in reference to a job Mr Dorrell has taken with KPMG, which his constituents claim is a conflict of interest.
More than 175,000 people have also signed a similar online petition calling on the Prime Minister to sack the former Health Secretary for the same reasons.
However, when the elderly group of three men and three women visited the surgery they were told to leave.
Mr Hill said: "Six of us went to Mr Dorrell's office at 4pm to try and get a meeting and hand over the disc with 2,000 signatures on.
"We were sitting there waiting and this guy came and told us we were trespassing. Then he said he was calling the police."
Mr Hill and his friends left a few minutes later only to be met outside the building by officers and squad cars.
"The policeman even joked that if he knew it was just a few pensioners he wouldn't have bothered coming," said Mr Hill. "It's a bit ridiculous really.
"Isn't it our right as constituents to see our MP?
"And surely his office can't call the police just because they don't like our reason for wanting to see him?"
Hanif Asmal, chairman of the Conservative Association, said the police were called because the group needed an appointment to see their MP and could not simply show up.
"They were trespassing," said Mr Asmal. "Because they didn't have an appointment."
Mr Dorrell, who was not at the surgery at the time, said he did not want to comment on the
However, he did say he did not agree with the petition.
"I've been a member of parliament for 35 years," said Mr Dorrell. "And I've always had outside interests and always been clear that I think members of parliament are better if they don't live inside a bubble."
