The SNP has claimed more than 1,200 people joined the party during the two hour long ITV leaders debate.
General Election campaign director Angus Robertson said: "This was an excellent performance by Nicola Sturgeon...
"The SNP gained more than 1,200 new members over the course of the debate, which reflects the energy and optimism which underpins our election campaign."
The party also tweeted out a picture during the programme showing Ms Sturgeon with the leaders of the other parties in her pocket.
Last night there wasn't one particular knockout blow but the political landscape in Britain does seem to be shifting.
Another day on the election trail and the campaign catchphrase is starting to bite.
Leaders' Debate shows was how our political horizon has suddenly changed as smaller parties did all they could to make themselves heard.
