The Anglican church in Scotland is to face de facto sanctions imposed by global church leaders next week for its acceptance of same-sex marriage.

Leaders of the global Anglican communion, meeting for five days in Canterbury, are expected to impose “consequences” on the Scottish Episcopal church along the lines of the punitive measures dished out to the US Episcopal church last year for its embrace of LGBTI equality.

The measures include a bar on membership of representational bodies and an exclusion from decisions on policy.

Scottish Anglicans voted overwhelmingly in June in favour of allowing same-sex couples to marry in church, setting the church on a collision course with the Anglican communion. The Anglican church in Canada is expected to follow suit.
