In pictures: Zimbabwe exile rally

Zimbabwean exiles have rallied in London to demand the right to work. A service for Zimbabwe was held at St Margaret's Church (left), in the shadow of Westminster Abbey.

St Margaret's is the parish church for the Houses of Parliament and has seen many services on historic occasions.

The Archbishop of York told the congregation that "God pulls down the mighty and raises up the humble".

Hundreds joined the rally in Parliament Square to call for exiles in "limbo" to be granted leave to remain.
