Mrs. May, who prides herself on a straight-talking veracity and a more compassionate form of conservatism than the other Iron Lady, has come under criticism for a series of U-turns.

She vowed she would not call an early election and then did just that. She supported Britain’s remaining in the European Union, yet is now overseeing its departure. She has been criticized for backtracking from new plans to finance care for older people, even as she has portrayed herself as the champion of those “just about managing” to get by.

The song “Liar, Liar” is the work of Captain Ska, a politically fueled ensemble of London-based session musicians who came to national prominence in 2010 with the first version of “Liar, Liar.” That was aimed at the austerity policies of the coalition government of Prime Minister David Cameron. The band was founded by Jake Painter and the song is being promoted by an organization called the People’s Assembly Against Austerity.

“We all know politicians like telling lies. Big ones, little ones, porky pies. Saying they’re strong and stable won’t disguise. We’re still being taken for a ride,” go the song’s lyrics, which take Mrs. May to task for cutting spending on education, the National Health Service and the police. They continue: “Nurses going hungry, schools in decline, I don’t recognize this broken country of mine.”

Proponents of the song have accused some broadcasters of censorship for not playing the song, including the BBC. The BBC said it would not be playing the song because of editorial guidelines requiring the broadcaster to remain impartial during elections.
