Let me correct myself (and this source), actually it was over 2/3 of Rada deputies:

Over 300 members of the 424-seat Ukrainian parliament have signed up to an interfactional association called “Values. Dignity. Family.”

The group has declared that its mission is to adopt laws to protect family values, popularize conservatism in Ukraine, and “resist attempts to undermine natural law for the sake of political trends.”

Specifically, the conservative caucus of lawmakers wants to tackle demographic issues and so-called “social evils” such as high divorce rates, abandonment of children, and abortion, Sviatoslav Yurash, an MP and leading founder of the group told the Kyiv Post.

“We understand that to tackle those social evils we need to cooperate with institutions that work with those groups (of the society). Ukrainian churches are by far the biggest social care provider,” he said.

“Life of the unborn should be discussed more seriously in Ukraine,” he added later.

In his words, supporting family values means promoting family cohesion, childcare, and family-building.

The idea for such a union of lawmakers in the legislature, he said, has been driven by increasing global debate over family values and marriage rights, as well as the clash between liberalism and conservatism.

“Various groups that are trying to claim legitimacy from some Western institutions claim that there is a fundamental consensus globally, and we have to get on with it, as if there is no other point of view,” Yurash said. “There is a very strong, very structured conservative point of view in the West. And it’s very important that this point is also transmitted into Ukraine.”

I think by "the West" they meant Poland, which had just banned practically all abortion.

The mentioned demographic trends in Ukraine were really bad. Like among the Russian Slavs, and having few multiplying Muslims unlike Russia. (And very little immigration.)
