Jo Shuter, the headteacher of King Solomon High School, has been banned from teaching for life over expenses abuses.
Ms Shuter was placed on gardening leave from the Jewish free school in Forest Road, Barkingside, pending a decision from the National College for Teaching and Leadership.
She recently admitted misconduct relating to claims she made in her previous role as headteacher of Quintin Kynaston Community Academy in St John’s Wood.
In an email sent to parents by King Solomon chair of governors, Stephanie Sollosi, which has been seen by the Guardian, it was confirmed Ms Shuter had been suspended from the school following the decision.
The email, shown to the Guardian by a parent, read: “The findings by the National College for Teaching and Leadership have now been published and confirm that Ms Shuter has been given a life-time prohibition order, which prohibits her from teaching indefinitely and therefore act as headteacher.
"Because of these findings, the Governing Body has had no choice but to suspend Ms Shuter from her role as Headteacher with immediate effect. Ms Shuter has 28 days to lodge an appeal against this decision.
“As I stated in my previous letter, the Governing Body's highest concern is that this situation has minimal impact on pupils during the lead up to the critical examination period and beyond. I repeat my request for your support in making sure pupils are focused on those issues and not distracted.
“I can reassure you that the Governing Body and Senior Leadership Team are entirely focused on the wellbeing and success of our children. To this end we are working very closely with Redbridge Council to secure a strong Head Teacher who will step in as Acting Head Teacher to lead the school. This will enable us to continue the progress that the school has made during this academic year.
“The plans to secure an experienced Acting Head Teacher are well advanced and I will confirm with you our decision by the end of the week.”
Ms Shuter took over at the free school in September 2013 and she was named headteacher of the year in 2007 for turning Kynaston Community Academy around, being awarded a CBE in 2010.
Amongst other expenses, she admitted charging the academy £7,000 for her 50th birthday celebrations, for her mobile phone bills, and the delivery of £1,500 of furniture to her home.
Two rival petitions were set up by parents, one calling for her to remain in her current job, and another insisting she should be sacked.
