She took a break during the height of the Troubles to run the Cove Bar in the Northern Irish border town of Newry.

In the 1990s, she moved to the Cabinet Office. During her time there, she was involved in the Coalition government’s so-called “bonfire of the quangos”.

Her son, Liam Conlon, was elected to Parliament in July as the Labour MP for Beckenham and Penge in south London. He received a £10,000 donation from controversial Labour peer Waheed Alli to help his campaign.
