Citroen has been hit by an unusual security breach ahead of a new product introduction, with a model of its Picasso-replacing MPV appearing on auction site Ebay.

Now a seven-seater and badged C4 along with an as-yet unconfirmed model designation, the MPV will be shown for the first time at next month’s Paris motor show before arriving in the UK late this year. Company insiders also point to a five-seater joining the range next year, with the current Picasso kept on as an entry-level budget alternative.
