Sandra Julia Gidley MRPharmS (née Rawson; born 26 March 1957) is a British pharmacist and politician who served as the Liberal Democrat Member of Parliament (MP) for Romsey in Hampshire from 2000 to 2010, when she lost her seat to Conservative candidate Caroline Nokes.

[3] She joined the Liberal Democrats in 1994, was elected as a councillor to the Test Valley Borough Council in 1995 and was, in 1997, the youngest ever female mayor of Romsey.

[4] After Romsey's Conservative MP Michael Colvin died in a fire at his home in Tangley on 24 February 2000,[5] Gidley was selected as the Liberal Democrat candidate for the resulting by-election.

[16] Whilst an MP, Gidley was claiming £1,638 a month[17] for a luxury flat with indoor swimming pool in London,[18] as well as £420 a month for food, and over £1,000 for Council Tax,[19][20] and was criticised when it emerged she and three other Lib Dem MPs, accepted a £18,700 cash windfall from the landlord of the Dolphin Square flat, in return for agreeing to an increase in their rent, which was funded by the taxpayer.

She was found to have "accepted one-off cash payment from the owners of an apartment block close to Parliament in return for agreeing to pay higher rent levels".

[24] In the 2019 Local Elections, Gidley returned to Test Valley Borough Council as the Councillor for Romsey Abbey ward defeating the Conservative Party incumbent.
