Sacked Haringey cabinet member Cllr Zena Brabazon has “categorically” denied leaking information to the media about the council’s dealings with Tottenham Hotspur.

Cllr Brabazon pledged to continue working hard as a ward councillor and as co-chair of the borough’s Fairness Commission after being removed from her post as cabinet member for civic services on New Year’s Eve.

Her comments followed rumours that leaks to the media over street cleaning around the new Spurs stadium could lie behind her sacking and the dismissal of her colleague, Cllr Peray Ahmet.

An article that appeared in The Observer newspaper on December 22 cited leaked memos from senior figures in the Labour administration detailing Tottenham Hotspur’s complaints over litter and fly-tipping on streets around the new stadium on High Road.

The memos claim Spurs – which was concerned about the negative impact this could have on the club – wanted the council to pay for street cleaning around the stadium.

But Cllr Brabazon said: “I did not leak anything about Spurs. I categorically did not do it.”

Commenting on the dismissals, council leader Cllr Joseph Ejiofor said he wanted to end “persistent personal conflicts” and create “a cabinet that works closer together to deliver our manifesto”.

But Cllr Brabazon – who stood against Cllr Ejiofor and lost in a Labour leadership contest last May – said: “The person who is in charge has to set the tone and lead the team. We were members of the team and worked really hard.

“I went in with a good heart. I worked solidly seven days a week – it was a full-time job for me.

“I have made a commitment to public life and I have not gone away. There is plenty of work I intend to do.

“I am committed to my ward and local issues, and I am going to carry on. Labour principles are the highest principles.”

Cllr Ahmet was also approached for comment.

Cllr Liz Morris, leader of the Liberal Democrat group, said a “divided Labour” was “causing chaos” at Haringey Council.

She said: “In just eight months, a quarter of Labour’s cabinet and deputy cabinet members have been sacked or resigned – one of them because he was convicted of drug offences.

“That followed the brutal purge of non-Momentum councillors last year. This turmoil in the first ‘Corbyn Council’ is a warning about the chaos we could expect from a Corbyn government.”

Ishmael Osamor, former deputy cabinet member for Broadwater Farm resident engagement, resigned as a councillor in October following his conviction for drug offences.
