“This is not linked to the migration issue. What we have is the bank’s systems and platforms are operating at a much better level. If you think about the preparation required on this it’s not something done overnight,” he said.
“It takes some weeks to be arranged for this communication exercise. It’s not an event driven by the weekend events,” he added.
Meddings said Pester, who was absent from a conference call with the media on Tuesday, was neither sacked nor resigned and instead his decision to leave had been reached by “mutual consent”.
“If we’d done it earlier the view would have been it was an inappropriate time to do it because he was leading with huge energy the remediation of the platform. To do it earlier would have been the wrong decision.”
In a statement, Pester said: “The last few months have been challenging for everyone at TSB.
“However, I want to thank all my colleagues across TSB for their dedication and commitment during this period and for their focus on putting things right for TSB customers.”
