MSPs will be urged to support reforms to the Gender Recognition Act by LGBT campaigners ahead of the first stage debate on the legislation at Holyrood.
Scottish Trans, part of the Equality Network, is set to host an event for supporters of the reforms outside of the Scottish Parliament in Edinburgh on Thursday afternoon.
There will be speeches from 12.45pm onwards, including from transgender people who will be affected by the reforms, with SNP, Scottish Greens and Scottish Labour MSPs also contributing.
