Jenny Chapman, Labour MP for Darlington, fumed after the ex-PM's astonishing Brexit intervention.
Mr Blair spoke on Friday morning urging the public to fight back against Brexit as he argued the people voted Leave “without knowledge”.
Speaking on BBC Radio 4, the Labour MP said: "There is much in there that I agreed with, but I think the fundamental premise of the speech is one that I do have to differ with Tony on this time.
Jenny Chapman criticised the former PM for not accepting the democratic referendum
“He doesn’t seem to accept the result of the referendum whereas the Labour Party has said that we do accept the result of the referendum.”
Mr Blair called for an uprising as he spoke during an event organised by Open Britain as he insisted that the people should change their mind.
He said: “I accept right now there is no widespread appetite to re-think. But the people voted without knowledge of the true terms of Brexit.”
Ms Chapman insisted she did agree with much of what the former prime minister had to say.
