A ringleader of the M25-blocking eco-group Insulate Britain does not have insulation in his own home, according to reports.
Eco-warrior Liam Norton's south-west London home is single-glazed, has no cavity wall insulation and uses gas central heating, reports the Sun.
Mr Norton, an electrician, is one of the leading figures in Insulate Britain - an Extinction Rebellion off-shoot campaigning the Government to reduce home heating emissions to zero.
The group infuriated motorists three times last week by blocking the M25 in a bid to put pressure on the Government to pay for all social housing to be fully insulated.
Mr Norton's property is owned by a housing association.
Mr Norton told the Sun: 'This is a good example of one of Britain's leaky homes and why we need the Government to get on with the job.'
MailOnline contacted Insulate Britain for a comment, but has so far not received a response.
