The Jewish Chronicle Power 100: The people shaping Jewish life in Britain

Coming in at No 76 (up from 92 last year) is Ken Livingstone:

Although he will be less influential after May 1 if he loses the London mayoral race to Boris Johnson, Mr Livingstone, 62, has impressed the Charedi community with his appreciation of its housing problems and his support for new projects. He has raised the prospect of a Charedi presence in the proposed major development of the Thames Gateway. In the short-term, he has held talks with community leaders about providing bigger houses for the strictly Orthodox. However, many Jews find it difficult to forgive his likening of Evening Standard journalist Oliver Finegold to a concentration-camp guard; insulting comments about businessmen David and Simon Reuben; and his hosting of controversial Islamic cleric Yusuf al-Qaradawi.

But nosing in front is David Toube (aka DavidT) of Harry's Place who storms in from nowhere to take the No 71 spot:

An up-and-coming name as key contributor to the well-regarded Harry’s Place blog, which is sympathetic to Israel, if at times critical, (sic) (emphasis mine) and exposes what it sees as left-wing hypocrisy. In professional life, the Oxford-educated blogger is an associate at the London office of international law firm Cleary Gottlieb, where he specialises in Financial Services Authority requirements to which regulated companies are subject. He has also authored legal guides and lectured in law at Queen Mary College, University of London.
