I suspect he may live round here. No stranger to controversy Lembit has been a vocal supporter of Oasis Church Waterloo (a former Prebysterian Church next to Kennington Police Station). Oasis is an evangelical church which is pro gay marriage - and got chicked out of the Evangelical Alliance because of that.
I don't think you are right about him marrying a Cheeky Girl - that seems to have been a relationship which did not lead to marriage.
He was of course a Lib Dem MP for many years(up to 2010) but of more relevance to road closures or not - Wikipedia says he is a long term supporter of the Motorcycle Action Group (MAG) of which he is apparently a director.
Don't know if Lindsay Avebury has engaged in this debate - but she is the other Liberal bigwig who might possibly be concerned - resides and very active in the Myatts Fields area (President of Longfield Hall trust I think).
