I've travelled to Dublin twice in the past month or so and there were posters at East Mids airport and Dublin.
We've just been on hols to Dorset and there were posters in some of the shops.
DD got questioned about her identity (asked to confirm name, date of birth, etc) when we travelled to Spain and Morocco in April - before Madeleine went missing. But she's now 10yo and her passport expires next year - she looks so different from the 6yo she is in the photo!
