police are focusing on a car park and impromptu campsite on a small peninsular on the west side of the lake. jim gamble, who was head of the child exploitation and online protection centre and was involved in the original madeleine mccann investigation, hopes the search will be significant. given the portuguese police are supporting and facilitating this search, then i think it s reasonable to be hopeful twofold. one is that the german police are continuing at pace and they are not taking off the pressure and they are continuing to invest resource. and number two, at some stage there has got to be a breakthrough. but madeleine mccann vanished 16 years ago, so the chances of proving what happened to her must now be limited. daniel sandford, bbc news at the arade dam. we are expecting that search to continue tomorrow. around the world and across the uk.
