Okay, let me preface this first: this tidbit of information comes directly from The Sun. Not the piece of crap North American tabloid but the piece of crap United Kingdom tabloid. This was the same paper that reported Doctor Who was ending after the fourth series, which ended up being refuted by millions of other reputable sources. So, take this information I write below with a grain of salt.

The Sun is reporting that Captain Jean-Luc Picard himself, Patrick Stewart, has agreed to guest star in the next Doctor Who series (season, to us in the Colonies) as a Time Lord. The agreement came after Stewart performed with Who star David Tennant in a summer production of Hamlet. According to the report, Stewart would team up with the Doctor in a two-part episode involving the Daleks (who just. Won't. Die.). He would play the role of a renegade Time Lord seen during the early days of the first Doctor Who series called the Meddling Monk.
