“The budget is a stressful time for the population. When I watched it, I was shocked to see Andrew laughing, yelling and making noises while Jeremy Corbyn was trying to make points about cuts to social care, services and the way austerity was affecting the poorest people in our communities.
“Videos and photos clearly show Mr Griffiths crouched down in between benches, out of sight of the Speaker, shouting over Jeremy Corbyn.
“No matter his political leaning, I would expect our MP to be concerned and to listen to speeches about cuts to our services and the way austerity is affecting real people. Instead, he laughed and jeered and shouted over the points.
“Andrew Griffiths is the MP for an area with a number of wards in the top five per cent of deprived areas in the whole country the issues Jeremy Corbyn was discussing are directly affecting his own constituents every day and he was laughing and jeering.”
He added: “He should be ashamed of himself – as should all MPs who mock, jeer, laugh and shout over speakers when they are trying to talk about real human issues.”
