2020 has to go down in history as Percy Pig’s biggest and best year to date. In the last six months alone, we’ve seen the launch of  Percy Pig ice cream , an entire Percy Pig Christmas collection , including Percymas pies, giant jars of sweets and even a giant Percy plushie, and most recently, the addition of Percy Pig Mini Bites and a Percy Pig Swiss roll to the M&S bakery section . But now there’s a brand new M&S Percy Pig cake joining the line-up, and it might just be the most exciting (and delicious) offering so far.
