NEARLY £14m is owed in child maintenance to single parents in the borough, according to figures published last week.
The figures, which were disclosed at the request of Labour MP Natascha Engel, show the child support debt nationwide, broken down by parliamentary constituency.
In Ruislip and Northwood, £2,946,000 is owed, and in Uxbridge, the debt is £5,308,000. Departed partners in Hayes and Harlington, however, has racked up the biggest bill, with a debt of £5,640,000.
Out of the 647 constituencies listed, these are placed 609th, 384th and 338th respectively.
Amongst the worst offenders nationally are Blackpool South and Milton Keynes South West, both of which have debts of over £10m, and Great Grimsby tops the list, with arrears of £11,069,000.
The report also states that over £129m is owed by parents whose whereabouts are unknown, and £30m is owed by spouses who are now living abroad.
In total, a massive £3761m is outstanding, yet less than a third of this amount is judged to be collectable.
Fiona Weir, Chief Executive at single parent charity Gingerbread, said: "Child maintenance is vital for children in separated families.
"We know from single parents that this is much-needed money which pays for items such as children’s clothes, school meals, trips and activities and childcare.
"Ultimately the responsibility for paying child maintenance rests with the non-resident parent, but the Child Support Agency has to do its job too in collecting debts and enforcing payment."
