Defra: Weeds - Identification of Injurious Weeds (PB4192) has pictures of spear thistle. Discusses difference to other thistles. The side bar menu will also take you to creeping thistle. Spear thistle = biennial, Creeping T = perennial

Under the Weeds Act 1959, the Secretary of State for Defra/Natural England can require action to prevent the spread of those weeds onto land used for grazing, to produce forage, and/or to grow crops. An unreasonable failure to comply is an offence. So, you don't need to eradicate these weeds; you may keep some on your land to feed the goldfinches and butterflies if you want. However if the spread is extensive, and someone has asked you to control them, and you have not, and then that someone complains to the S of S, you might find you are legally obliged to prevent their spread, whether by root or seed, onto other land, and in essence this would probably mean major control works, at your own cost.
