Britain's decision to leave the EU has not prompted a boost in support for Scottish independence, according to a YouGov poll that undermines the SNP's push for a second referendum.

Some 53 per cent of Scottish voters oppose independence, while 47 per cent support the move - almost identical figures as before the Brexit vote last month.

Last month Nicola Sturgeon, the Scottish First Minister and SNP leader, responded by saying she was considering calling a second referendum on independence.

The findings came as London enjoys a "Brexit boom" in tourism as visitors head to the capital in record numbers after the pound dropped in value.
