UKIP Wales has confirmed former conservative MP Neil Hamilton has been chosen as group leader of the party.
Under party rules, UK leader Nigel Farage appoints the party's Welsh leader - currently Nathan Gill - but the group leader is a separate post.
Mr Hamilton was understood to hold the support of at least three newly-elected UKIP Assembly Members.
Earlier this week leader Nigel Farage described Neil Hamilton's appointment as 'unjust and a deep act of betrayal'.
It's the first time all sixty newly elected Assembly Members will meet at the Senedd. The position of First Minister will also be announced.
