A new portrait of Prince Philip has been unveiled to mark the 50th year of the Duke's presidency of the City & Guilds of London Institute. The CGLI helped to found the City & Guilds College (which merged with the Royal College of Science and Royal School of Mines in 1907) over a century ago and still has links with the college and the City & Guilds College Union.

The CGLI offers vocational courses in a wide range of areas, ranging from agriculture to administration. "We have witnessed substantial change since the duke became president," said David Young, chairman of the CGLI, "we are now at the forefront of the very latest developments in learning." Most Imperial College students will be most familiar with the CGLI's role in setting typewriting exams, with the BBC coverage of last year's Lord Mayor's Show referring to the C&GCU as "typists".

City & Guilds was established in 1978 and awarded a Royal Charter in 1900. Prime Minister Tony Blair is among those who have registered with the organisation for an IT qualification (though given his expressed inability with technology, it seems unlikely that he's ever going to finish it).
