Conservative pensions minister Ros Altmann has been expelled from the Labour Party, according to reports.
The Huffington Post reported that Altmann, who was made a peer by Prime Minister David Cameron, and given the pensions brief in May had been a Labour Party member since March 2014.
Altmann renewed her Labour membership this March, according to the website, but was kicked out of the party after it was revealed she had been given a vote in this month's leadership election.
The site quotes a Labour source as saying Altmann was expelled for "not supporting our aims and values, by serving as a minister in a Tory government".
Commenting on the news, Hargreaves Lansdown head of pensions research Tom McPhail said it was widely known that Altmann had advised the Blair government.
She was also a close ally of Steve Webb, the Liberal Democrat pensions minister under the coalition government too.
McPhail said: "Ros was brought into the current government because she has very considerable expertise in pensions and because she has been an effective campaigner for justice on pension related issues. Her political sympathies are less important than whether she can perform a good job as the pensions minister."
