The 90-minute encounter last night saw Labour leader Ed Miliband, UKIP leader Nigel Farage, the Green Party’s Natalie Bennett, Plaid Cymru's Leanne Wood and Sturgeon clash on a range of subjects, from austerity through to immigration.
According to FleishmanHillard, there were 450,000 mentions of the debate on Twitter, fewer than half the number of tweets about the previous leader’s debate earlier this month.
Sturgeon had a 74 per cent positive sentiment rating on Twitter, a drop on the 84 per cent the SNP leader enjoyed during the ITV debate but still a clear lead over Bennett, who came second last night on 65 per cent.
Wood enjoyed a 56 per cent positive rating while Miliband scored 55 per cent and Farage came last on 32 per cent.
Despite coming last in terms of positive sentiment, both Miliband and Farage improved social sentiment on their ITV debate appearances when they scored 28 per cent and 22 per cent respectively.
The UKIP leader was judged to have lost the greatest amount of positive sentiment during the course of last night’s debate, which saw positive support drain away from 44 per cent half way through to 32 per cent at the end.
Conversely, Sturgeon and Miliband both increased their sentiment during the debate, with the SNP leader rising from 70 to 74 per cent and the Labour leader rising from 52 to 55 per cent by the end of the discussion.
