This came out of a row in Britain over an investigation into schools in Birmingham. Unlike the US situation, what brought this about was a charge that Muslims were trying to take over schools in Birmingham and alter the lessons to support Islamic Ideals. The term you can search on to find this is Trojan Horse Investigation, along with Birmingham.

One of (many) things charged was teaching creationism. Others were teaching in sex ed that wives weren't allowed to "say no" and must submit to their husbands.
How much of this is true depends on who you ask and, no surprise, it's quite a controversy.
But, to put it in context, this came up in response to charges of Islamic influence. Apparently any Christian state funded schools teaching creationism didn't raise this level of concern.
