The 2012 contest reaches the penultimate heat, from Salford, with Russell Davies in the chair. This week's competitors come from Hull, Glasgow, Bristol and Leeds.

Among the questions they face will be: What's the usual title given to the poem by Robert Browning that begins 'Oh, to be in England, now that April's there'?

And: Which physicist gave his name to zones of highly energised charged particles trapped at high altitude in the earth's magnetic field?

The winner today takes one of the last remaining places in the semi-finals, and takes a crucial step closer to the coveted title of Brain of Britain 2012.
