A claim that same-sex marriage in Scotland could lead to “sexual chaos” has been branded offensive by independent MSP John Finnie.

Amy King put forward a petition to Holyrood, urging the Scottish Government to retain the current definition of marriage as a “union between one man and one woman”.

The Hamilton Advertiser reports she said: “Schools would be expected to promote same-sex marriage to children as equal to man-woman marriage, creating confusion and going against the wishes of many parents.

“If marriage can be redefined in this way, it could then be further changed to allow polygamy. For example, Canada has legalised same-sex marriage and litigation is now under way in one Canadian province to legalise polygamy.”

In response, MSP John Finnie said: “I have had due regard to it. I have read it thoroughly. I did find the content offensive. We should take no action on it.”

Yesterday, the Scottish Government unveiled its draft equal marriage bill.

All religious institutions – including the Church of Scotland – will be free to decide for themselves if they would like to provide marriages for gay couples as part of the plans.

Ministers have already decided they want to make the change, and now need to consult on proposed legislation to be put to the Scottish Parliament.
