In a few weeks, HSJ, recruitment consultancy Harvey Nash and management consultants Ernst & Young will be collaborating with a panel of experts to decide the HSJ50 for 2007 - the definitive list of the 50 most influential people in healthcare.

Last year's panel declared that Paul Corrigan, health adviser to then prime minister Tony Blair, was the grand fromage of health, easing health secretary Patricia Hewitt into the number two spot.

This year the battle for the top place is even more complex. New health secretary Alan Johnson has a fight on his hands with not only Lord Darzi - surely one of the most influential junior ministers in the entire government - but NHS chief executive David Nicholson, ranked number three last year after barely days in the job. Or is Greg Beales, Gordon Brown's health adviser, maintaining a vice-like grip from Number 10?

Among others to watch, the panel will have to decide whether the tough talk of British Medical Association chairman Dr Hamish Meldrum, coupled with the government's desire to engage with clinicians, warrants him a higher place than the 19th secured by his predecessor.

And what of shadow health secretary Andrew Lansley? Is the Tories' health strategy and its opposition to accident and emergency closures shifting the policy debate, or will he slip down the rankings?

The judges would be delighted to hear your views on who should be where in the HSJ50 2007, please e-mail me at richard.vize@emap.com.

We will publish a selection of your submissions on hsj.co.uk, and unveil the final rankings in November.
