Citroen is offering to pay the £35 car tax on any of its models which produce less than 120g/km until July 31.

This is in addition to the £500 part exchange cashback offers on many models, when customers trade-in older, more polluting vehicles.

The French manufacturer has 22 models that fall into the sub 120g/km category, including the C1, C2, C3 and C4.
