If you passed your test after January 1, 1997 and before the January 19, 2013 you are able to drive a vehicle that weighs up to 3,500kg towing a trailer of up to 750kg, bringing total weight allowed to 4,250kg. You may also tow a trailer over 750kg as long as the weight of the trailer is no more than the unladen weight of the towing vehicle, up to a combined weight of 3,500kg.
The combination doesn't work your fiesta plus trailer needs to weigh less than the empty mondeo
Finding stuff comflicting this though, would probably need to make a phone call to find out the exact rules
