Writing on Facebook, a spokesperson said: "Since our tumultuous season 12 finished airing at the end of February, our intrepid team have been grabbing the chance to rest up, relax, or else fit in some quick theatrical work before filming commences again!
"But today marked an important celebration – our team gathered at a plush venue in the west end of London for their first get-together before the cameras roll again and the scripts drop through the doors. "We hear the producers organised the team a wonderful meal - there were speeches, lots of laughter and many reunion hugs!"
