It is the latest move by furious campaigners for the UK to stay in the EU, millions of whom have signed a petition calling for a second referendum. Johnson today used his column in the Daily Telegraph to try to build bridges with Europe with those who voted remain.
He wrote: "They are our neighbours, brothers and sisters who did what they passionately believe was right".
"We must reach out, we must heal, we must build bridges - because it is clear that some have feelings of dismay, and of loss, and confusion."
He added that the 'climate of apprehension' had been made worse by exaggerated warnings during the campaign.
