For the first time in my life I had to drive to Battersea, South London at short notice. When I got to crossing the river bridge, I tried to get into the left lane and go west along Embankment to get back into the gardens, but with so many cyclists etc I was pushed to go straight on and to take next left in Chelsea to get back onto Embankment which I did some three minutes later. The Congestion Charge camera clocked me in Lower Sloane St. I have said the above in a letter and that the fine is two weeks of my pension money, but they say I must pay.
