Webservice action to delete item in another list

I would like to use a web service in Nintex Workflow 2010 to delete an item in another list on another site collection.
I tried to use the UpdateListItems method in the Web service message:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:m="http://schemas.microsoft.com/sharepoint/soap/">
  <soap:Header>
  </soap:Header>
  <soap:Body>
<Batch OnError="Continue" ViewName="{43B09A1F-DF42-48D1-93E9-6D6B1D2BE5F0}"><Method ID="1" Cmd="Delete"><Field Name='ID'>3</Field></Method></Batch>
  </soap:Body>
</soap:Envelope>

But I always receive an error: Value cannot be null. Parameter name: requestUriString 

Does any one has a working flow for this?
