Tributes from Gordon Brown and Ed Balls to Wolfson Hillel Primary head Sharon Margolis were read out at a retirement lunch for Mrs Margolis, who has left the Southgate school after 15 years.

Praising the commitment and vision of Mrs Margolis, Mr Brown wrote that “at Wolfson-Hillel, you have built up a great school”. In his message, Mr Balls, the Education Secretary, noted that “the excellent facilities and reputation the school now enjoys is due to your leadership skills”.

He further commended her for “providing a safe, supportive and vibrant learning experience”. The 120 lunch guests included current and past staff and governors and other Jewish educational representatives.

Mrs Margolis plans to make aliyah to spend more time with her children and grandchildren, who live in Israel.

Lindy Grant will be acting head until Jason Marantz takes charge in September.
