Labour's shadow education secretary, Tristram Hunt, has been criticised for being "condescending" after telling a voter to "stop moaning" and "do some work".
Hunt was responding to a question on Twitter about the party's education policy. It started off well, an object lesson in how politicians should engage with voters in 2015.
@TristramHuntMP can you point me to the Labour education policy for this election round?
A voter asked for more information and Hunt replied with the website. Perfect.
@curv_org @TeacherROAR certainly can - http://t.co/gUpexY553b
But then Thomas Mann claimed Labour's education website only had "soundbites" and wanted more in-depth policy.
@TristramHuntMP @TeacherROAR that website only contains soundbites. Can I see some detail covering the full complexity of education policy.
At which point Hunt demonstrated how not to engage with voters in 2015, telling him to "stop moaning".
@curv_org @TeacherROAR Stop moaning. Read the speeches. Do some work. Your industry will be rewarded,
Mann told politics.co.uk that Hunt's words meant Labour had "definitely lost my vote".
"I felt very condescended by him," Mann said. "I felt that he was treating me like a little person.
"I think politicians have lost the idea of who their employers really are and who they are meant to serve."
