Natalie Bennett's 'car-crash' radio interview appears to have boosted Labour's chances of winning more seats in London.
A new opinion poll gives the party an increased lead at the expense of the Greens.
The new survey opens up Labour's lead over the Conservatives in London to 12 points.
The poll by YouGov for the Evening Standard puts Labour on 44%, Conservatives 32%, Ukip 10% and the Liberal Democrats 7%.
If the results are repeated on May 7th, Labour could win seven of its 12 target seats in the capital.
The Greens have dropped from 8% in January to 5% following Benett's LBC interview when she admitted to 'brain fade'.
