A Jewish primary school sent parents an email urging them to vote in the local elections, and naming three Conservative councillors as people who had “helped” the school.

Nancy Reuben Primary School, in north London, sent the message to over 100 parents on the day of the local elections last week.

It said: “Please remember to vote this evening, and if you are in the Hendon & Finchley Borough Mark Shooter, Councillor Braun and Anthony Finn have been very helpful in all our travel problems and in any issues we have had.”

All three were Tory candidates for Hendon ward of Barnet council, and were elected.

One parent, who wished to remain anonymous, complained that the school had tried to influence voters.

The school is a charity and falls under the Charity Commission regulations.

A spokesperson for the Commission said its guidance “makes it clear that a charity must not give its support to any one political party” and “must never indicate to its supporters which candidate to support in an election”.

But the Commission would not say whether the school had broken its rules.
