Exclusive: Caroline Lucas Condemns ‘Moral Failure’ Of Remain Campaign To Defend Free Movement

And in an attempt to reach out to Brexit voters she will say “thank you” to them for giving “the establishment a much-deserved kicking” and expressing what she sees as “a collective howl of rage” over how the country was being run. 

“That response was justified then –  and is justified now,” she will say. 

She believes the “core message at the heart of the Brexit vote” was that “the status quo in this country is intolerable for huge numbers of people”.  

“It is right and reasonable to be furious,” she will say.  

Their vote was driven by Britain’s “gross inequalities”, she will claim – something Brexiteers fiercely contest – citing reports of interregional inequality 50% higher in the UK than in France and Germany. 

“In short, this is a country where what dictates your success isn’t how hard you work, or how much you care,” she will say.  “It’s not your passion or your commitment

“No. This is a country where your success is dictated by your postcode, the income of your parents, the year in which you were born.

“The lie at the heart of the Leave campaign was that this downward spiral – indeed, this negative double helix of inequality and insecurity – could be reversed by leaving the EU.”

Lucas’ speech comes as Theresa May prepares to put her Brexit deal before MPs next Tuesday. 

It is widely anticipated that MPs will reject her deal but it is not yet clear what step the prime minister will take next.

She has a range of options, including suspending Article 50, attempting to renegotiate with Brussels, opting for a soft Brexit, a no-deal exit and calling a second referendum.
