There is "no doubt" infighting surrounding Jeremy Corbyn's leadership cost Scottish Labour votes in the Holyrood election in May, Kezia Dugdale has said.

Scottish Labour came third in the election behind the Scottish Conservatives and SNP.

The result marked the party's worst showing at a national election in Scotland since 1910.

Dugdale described the current state of the Labour Party as an "ugly mess".

When asked by STV News if the infighting cost her party votes in May, Dugdale said: "I am the leader of the Scottish Labour Party.

"I take full responsibility for the election campaign we had. But there is no doubt that the infighting had an impact.

"That is not me apportioning blame, that's just me doing the job I am supposed to do - listening to voters, understanding their concerns, understanding why they felt they couldn't vote for us last time".

The party's only Scottish MP Ian Murray was one of 20 shadow Cabinet members to resign from his post following Corbyn's decision to sack his shadow foreign secretary Hilary Benn.

A motion of no confidence in Corbyn's leadership was then passed by Labour MPs by a vote of 172 to four.

Following the no confidence vote, Dugdale called on Corbyn to "reflect" on the result and said she would "not carry on" if a similar situation transpired among Scottish Labour MSPs.

Stephen Low, a trade union official and campaigner for Corbyn's re-election in Scotland, said: "I find that quite a difficult idea to sustain.

"Jeremy took very little part in the election then. It was led front and centre by Kezia. The damage to Labour's prospects was done the year before when under Jim Murphy's leadership.

"Scottish Labour MPs went from being a group to a solo act."

Ballot papers began being distributed to eligible voters on Monday.
