Only two charities have been struck off the register of charities since the turn of the century for having political purposes, according to information given to Parliament last week.
Andrew Hind, chief executive of the Charity Commission, revealed the statistic in a written response to a question from Margaret Moran, Labour MP for Luton South.
Hind said that of 736 non-statutory investigations and statutory inquiries carried out by the regulator in the past three years, 29 had related to political activity.
"These 29 investigations were to examine allegations or concerns about inappropriate political activity and campaigning by charities, or charities making political donations or giving support to a political party," he wrote.
Hind said that charities that broke the rules on political campaigning were asked to mend their ways, and that revocation of charitable status was not a "legal remedy".
But charities that were found to have a political purpose were removed from the register, he added. He said this had happened twice in the past 10 years.
He did not name the two organisations but a commission spokeswoman said that Concern for Family and Womanhood and Brit Trumpeldor of Great Britain had been removed from the register in 2001 and 2004 respectively.
Brit Trumpedlor of Great Britain had a charitable purpose "to educate Jewish youth in good citizenship and in the values of Jewish heritage and tradition." The Commission found that its activities were in furtherance of a political purpose, it had no properly appointed trustees and had submitted no accounts for four years.
