AFAIK Hurn airport and Odiham are the current "leaders", both with the last measurable rainfall on 30 June, so that's 35 days up to yesterday. It looks pretty well certain there will be no appreciable rain at either of those for at least a week (although never say never in Britain!)
Edit: actually I see Hurn is now out of the running as it had 0.4mm of rain on Wednesday. (The total drought there started one day earlier than Odiham, in fact, with the last previous rainfall on June 29, so it managed 34 days in total.)
