Taylor Swift: Khan denies conflict of interest over Wembley performance

In the summer, the company organized fan zones where people could watch the Champion’s League final.

Last year, LS Events won a place on an elite list of “approved suppliers” allowed to organize outdoor events on behalf of the Mayor of London.

There are only six companies on the approved list and they bid against each other or can sometimes bid unopposed for contracts as they arise.

City Hall says this list has been drawn up by Greater London Authority officials using normal processes and an open tender.

When the tickets to see Taylor Swift were first offered by LS Events in June, City Hall said they were “discussed with agents who had nothing to do with the tender process.”

They were only accepted by the mayor on the eve of the concert and “no one who received a ticket was involved in the purchasing process.”

The spokesperson added: “The mayor has no conflict of interest. The mayor has no involvement whatsoever in the tender process.”

Neil Garratt, leader of the London Assembly Tories, said: “Awarding a contract to a company after accepting the offer of generous hospitality during the bidding process would be an outrageous breach of ethics.

“It’s explicitly banned in the GLA hospitality rules, I can’t believe the people in the mayor’s office didn’t know.

“Was the late filing and failure to mention the company name just an accident, or was it an attempt to conceal serious wrongdoing?”

City Hall has so far refused to explain why the mayor declared the donation ten days late.

But it meant the details were left out of the town hall register for the public and media to see at the height of the ‘freebies’ controversy that engulfed the Labor leadership in the first three weeks of September.
