The seat is composed of all but a small eastern portion of the London Borough of Camden and extends from most of Covent Garden and Bloomsbury in the heart of the West End of London through other areas of NW1, north and in elevation terms upwards through trendy and economically diverse Camden Town to the affluent suburb of Highgate in a long strip.
Property prices in many neighbourhoods of the seat are among the highest 25% seen in London. A four bedroom home on Gloucester Gate is likely to reach an asking price of around £6 million, whilst on Cambridge Gate, located closer to the Inner Circle, the same amount of money is only likely to secure a flat. Yet this is accompanied by high levels of rented and social housing, particularly in the middle of the seat around Camden Town and Kings Cross where sharing in the lowest 10% of London prices and mostly social housing, in Stanhope Street is a high rise purpose built block, where a one bed flat could potentially be secured for around £200,000. – Kings Cross, St. Pancras and Euston railway stations are all in the seat.
With so many contrasting parts, all three main parties have a solid voter base in the seat, though Labour has held on fairly comfortably against split opposition.
Following their review of parliamentary representation in North London, the Boundary Commission for England recommended the creation of a modified Holborn and St. Pancras constituency. To effect this change, parts of Highgate ward, Gospel Oak ward, Haverstock ward and Camden Town with Primrose Hill ward were transferred from the former constituency of Hampstead and Highgate.
Gospel Oak, particularly towards Kentish Town, has high deprivation levels, but neighbouring Highgate ward has low deprivation levels, producing little change overall. (Gospel Oak had previously been part of the constituency, but had been moved to Hampstead and Highgate at the last review.) The electorate of the new seat would have been 85,188 if it had existed at the 2005 General Election the figure has since risen further and at the 2010 general election, it now has one of the highest electorates in London.
