The couple who reported Boris Johnson to the police and recorded his row with girlfriend Carrie Symonds wrote an anti-Brexit play partly funded by the EU.
Eve Leigh, 34, and husband Tom Penn, 30, were listening through the walls as Mr Johnson and Ms Symonds argued as the couple live in the flat above.
Mr Penn and wife Ms Leigh called the police after they claimed they were 'frightened and concerned' by noises coming from the flat in the early hours of Friday morning.
In a statement last night Mr Leigh said his motivation for informing the police was not political and that 'the extent of my involvement in politics' was merely voting remain in the 2016 referendum.
But in a now deleted Twitter account, Ms Leigh wrote that she, 'just gave Boris Johnson the finger, this weekend is unstoppable' and this summer, she wrote how 'all Tories suck'.

A source close to Ms Symonds said the gesture came after Mr Johnson spoke to her while taking down anti-Boris posters, which Ms Leigh said she played no part in.
She also previously claimed Theresa May had brought in 'insanely cruel policies', that Brexit was 'racist' and the Home Office was 'lower than vermin' as well as criticising Mrs May's policies as 'insanely cruel towards immigrants, poor people and people of colour'.
Ms Leigh also wrote: 'If you feel sorry for her [May], have a look at yourself.'
Her anti-Tory tweets on her account, which had been active for seven years, dated back to the Occupy London protests in 2012 when Mr Johnson was the capital's mayor.
That year she also co-wrote a production about the Occupy London protests that camped out at St Paul's Cathedral.
Last week wrote on Twitter that Tories were 'pretending to respect the memories of the Holocaust dead'.
Ms Leigh is an 'experimental playwright', a former palm reader and her partner is a also performs close-up magic, according to an interview in The Stage.

Earlier this year, one of her plays appeared in the Brexit Stage Left festival in London, a celebration of European theatre sponsored by a network of dramatists that is part-funded by the European Union.
Brexit Stage Left saw a group of stand-up comedians touring Europe performing 'cutting edge' plays from across the EU'.
The project held in January
