Labour's defeat to Plaid Cymru in the Rhondda constituency is a "terrible loss", according to Lord Peter Hain.
Leighton Andrews, Assembly for Wales member for Rhondda between 2003 and 2016, lost by a majority of over 3,000 to Plaid Cymru's Leanne Wood.
The last time Plaid held the seat was in 1999.
The Welsh reality star has suffered a debut election defeat - and revealed he had a tough time on the campaign trail.
Labour suffered a "terrible" defeat in Rhondda but has already won 16 Welsh Assembly seats as it looks to record a fifth term in office.
