Baking queen Mary Berry will flick the switch on this year's Christmas lights in Amersham next month. 

The national treasure will light up the town and officially kick off the Christmas festivities on December 9 as part of the Amersham Christmas Festival - organised by the Amersham Action Group. 

Sycamore Road will be transformed into a Christmas market with a range of attractions including an entertainment stage, fun fair and food stalls. 

Crowds will be entertained with performances from the Amersham Rock Band, Amersham Community Choir, Amersham Band and Chesham All Girls Band before Mary switches the lights on at around 4pm. 

Santa will also make a return to his grotto in St Michael's Church. 

The festive event will take place from 10am to 5pm.
