Tractors have started to park up outside the Houses of Parliament as preparations for the start of today's annual Back British Farming Day event commences.

Now in its ninth year, the initiative puts a spotlight on the importance of farming, such as providing food for the nation, its environmental efforts and its contribution to the economy.

The NFU-organised event, which gets underway on Wednesday, starts in Westminster with a breakfast reception at the House of Commons.

More than 100 MPs are expected to attend.

A red Massey Ferguson tractor arrived in the Old Palace Yard outside of parliament this morning, with NFU officials greeting MPs and members of the public to share the story of Britain's farmers.

Andrew Griffith, MP for Arundel and South Down, was first off the mark to visit and hear the message for Britain's farmers, followed by Rachel Gilmour, MP for Tiverton and Minehead, and Connor Naismith, MP for Crewe and Nantwich.

As part of the annual initiative, farming groups call on the UK government to do more to support British farmers and food production.
