Mr Johnson, who missed out on the Green’s third target seat of Lewisham Deptford, urged disaffected Lib Dems to defect to the Greens.
On his twitter account Mr Johnson urged: “Leave the lib dems. Join the greens!”
He also criticised Lib Dem voters saying: “I bet all those greenies and lefties who voted Lib Dem are feeling total to**ers now.”
