Reverend Doctor Simon Topping came to prominence during his time in Birmingham and his work on the British chapter of the Jubilee 2000Drop the Debt campaign. In 1998 he helped to initiate a human chain around central Birmingham during the G8 meeting of world leaders in the city. The campaign resulted in the relocation of the G8 conference meeting to the outskirts of the Midlands. In 2003 he co-founded the Saltley Gate Peace Group, an inter-faith initiative, launched in response to the build-up to war in Iraq.
In 2001 Topping caused controversy when he designed a black poppy to 'highlight the problems of world poverty'. Members of the Royal British Legion were allegedly angered by the use of the poppy due to its connotations with Remembrance Day. The minister continued to campaign for the cause right through to Make Poverty History.
