Price discrepancies - Telegraph

[TUK020]

I usually use the key movements up/down in the Telegraph to keep an eye on shares that are moving.

This morning the Telegraph shows one of the major gainers was WPP, rising 16% to close at 1026.50.

HYPTUSS gathered Yahoo data this morning before open is showing 881.
Hargreaves Landsdowne is showing 879.

Is the Telegraph data wrong, or showing overnight trading?

WPP’s website itself is showing 881p. Anomolies do sometimes happen with trades going through at strange prices, this does sound like the Torygraph has got it wrong!
