The last four semi-finalists fight for the three remaining spots in the grand final. Today's Bespoke Bake challenge is to create an afternoon tea menu for special clients the Chelsea Pensioners - which must include a loaf, a fondant fancy and a Chelsea bun.

The first of a three-day grand final sees judges Mich Turner and Peter Sidwell upping the stakes for the remaining three bakeries with the Market Challenge. The establishments are challenged to create a range of goods to sell to lunchtime shoppers at London's historic Old Spitalfields Market.

The three remaining bakeries face the penultimate challenge - the iconic bake. The judges ask them to use all of their ingenuity and creativity to come up with a product that best represents their companies, and can put their regions on the map. However, not everything goes to plan when they are given the chance to shine.
