London mayor takes down summer house built on balcony of his Islington home following complaints that it was erected without planning permission.
Boris Johnson, the mayor of London, faced embarrassment today after it emerged he has taken down a wooden shed he built on the balcony of his home following complaints to his local council.
As mayor, Johnson is in charge of planning issues in the capital. But he appears to have overlooked the rules when he erected the shed on a first floor balcony at his home in Islington more than two weeks ago.
Neighbours complained that it was an “eyesore” and that it should not have been put up at his Georgian house, which is a Grade II listed building, without planning permission.
