VIEWERS will see tonight how TV presenter Chris Evans coped with cleaning Britain’s tallest tower.

The One Show host cleaned the windows yesterday outside One Canada Square in Canary Wharf as part of a ‘grin and bear it’ stunt for Children in Need.

People were asked to vote for one of the presenters - Evans, Jason Manford or Alex Jones - to do a job out of their comfort zone, with the idea raising more than �100,000 for the cause.

The film of how the Radio 2 DJ got on as a window cleaner will be shown on Children in Need’s live show from 7pm on BBC One, with Evans admitting he was “petrified”.

He tweeted: “Couldn’t twee while I was up there, no loose objects allowed and no signal! Should be a great film,I was properly ******* myself,” adding before the stunt: “All for the kids. That’s what I keep telling myself at least.”
