U.S. Rep. Michele Bachmann will attend the funeral of former British Prime Minister Margaret Thatcher on Wednesday as part of a congressional delegation.

In the waning days of 2012 presidential campaign, Bachmann often compared herself to Thatcher, the prime minister known as the "Iron Lady" because she stuck to strict conservative economic and political positions despite public opposition.

Days before the Iowa Republican caucuses in January 2012, Bachmann told crowds that: "We need another Margaret Thatcher, another Iron Lady."

Bachmann also ran campaign ads in Iowa calling herself "America's Iron Lady." The comparison came in the days surrounding the theatrical release of a biographical movie, starring Oscar-winning actress Meryl Streep, about the Thatcher's life.

House Speaker John Boehner selected Bachmann for the delegation, which will include Republicans Marsha Blackburn of Tennessee and George Holding of North Carolina.

Thatcher, who served as prime minister from 1979 to 1990, died April 8.

"Not only was Margaret Thatcher a role model for conservative women across the globe, but she was also one of the most consequential political leaders of our time," a statement from Bachmann read, in part. "While we mourn her loss, we also remember the extraordinary legacy she left behind. May the great Lady rest in peace."
