LONDON British parliamentary Speaker John Bercow will face MPs on Monday for the first time since a row erupted over his recommended candidate for the post of clerk of the House amid growing disquiet among critics of the choice of Australian Carol Mills.

Mr Bercow will reportedly make a statement in the chamber about the choice of Ms Mills, who is head of the Department of Parliamentary Services (DPS) in Canberra.

Members have voiced concerns about her lack of knowledge of Westminster procedures and believe she is too inexperienced for the prestigious $A365,060-a-year position, which combines the clerk's duties as a key constitutional adviser with the role of Commons chief executive.

She has been dubbed the "Canberra caterer" because her responsibilities at the Australian Senate are said to include managing kitchens and cleaning.
