On a point of order, Mr Speaker. Thank you for taking this point of order at this stage in our proceedings. My concern is the accountability of Network Rail to Parliament. You may recall that twice in the last month I have raised the issue of the closure of Suggitts Lane level crossing in my constituency. Yesterday, Network Rail moved in and put up security barriers to close that crossing, despite objections from me and from North East Lincolnshire Council, a petition signed by 4,000 residents and a request from the Rail Minister to review the decision. In view of that, can you offer guidance about how I, or indeed Parliament, can hold Network Rail accountable for this action?
