BibTeX, biblatex and biber ⇒ Change use of ampersand (&) to "and" for in-text citations

[jjh]

Hello,
I would like to change the default in-text citation from something like the following:

(Smith & Jones 2005)

to:

(Smith and Jones 2005)

I am currently using the 'harvard' package and bibliography style 'apsr'

Thank you.

From the manual of the harvard package:

3.4 Conjunction Style
In the previous examples for the agsm bibliographic style a “&” character
is used to signify conjunction between a pair of names or between the last
two names of a list of names. Similarly the word “and” is used for the dcu
style. With these two styles this convention may be overwritten by using
\renewcommand to redefine the command \harvardand. This should be
done after the \citationstyle command (if used) as this command resets it to
the default for the style selected.

As far as I can see, the apsr style uses the \harvardand command in the same way as agsm.
