Somebody spent money to find out what we already know.

Visitors are more likely to be greeted with a grin than a grimace up North, while Londoners are loath to offer assistance, it has been revealed.

Yorkshire and Humberside was the area in which travellers expected to find the most helpful locals, according to a survey by Best Western Hotels.

In contrast, London was seen as being by far and away the region with the least helpful people.

After Yorkshire and Humberside, the most hospitable regions were Scotland and north west England, followed by north east England.

Just 2% of the 2,000 polled said Londoners were the most helpful, while 49% rated those living in the UK capital the least helpful.

The next most inhospitable locals were to be found in Wales followed by south east England.
